**Certus-NX Family Data Sheet**
## **1. General Description**
The Certus™-NX family of low-power general purpose FPGAs can be used in a wide range of applications across multiple markets, and are optimized for bridging and processing needs in Edge applications. It is built on the Lattice Nexus™ FPGA platform, using low-power 28 nm FD-SOI technology. It combines the extreme flexibility of an FPGA with the low power and high reliability (due to extremely low SER) of FD-SOI technology, and offers small footprint package options with a high amount of I/O per mm[2] . Design security features such as AES-256 encryption and ECDSA authentication are also supported.
Certus-NX supports a variety of interfaces including PCI Express (Gen1, Gen2), SGMII (Gigabit Ethernet), LVDS, LVCMOS (0.9–3.3 V), and more.
Processing features of Certus-NX include up to 39k Logic Cells, 56 multipliers (18 × 18), 2.9 Mb of embedded memory (consisting of EBR and LRAM blocks), distributed memory, DRAM interfaces (supporting DDR3, DDR3L, LPDDR2, and LPDDR3 up to 1066 Mbps × 16 bits data width).
Certus-NX FPGAs support fast configuration of the reconfigurable SRAM-based logic fabric, and ultra-fast configuration (under 3 ms) of its programmable sysI/O™. In addition to the high reliability inherent to FD-SOI technology (due to its extremely low SER), active reliability features such as built-in frame-based SED/SEC (for SRAM-based logic fabric), and ECC (for EBR and LRAM) are also supported. Dual 12-bit ADCs are available on-chip for system monitoring functions.
Lattice Radiant™ design software allows large complex user designs to be efficiently implemented in the Certus-NX FPGA family. Synthesis library support for Certus-NX devices is available for popular logic synthesis tools. Radiant tools use the synthesis tool output along with constraints from floor planning tools to place and route the user design for the Certus-NX device. The tools extract timing from the routing and back-annotate it into the design for timing verification.

**Certus-NX Family Data Sheet**
## **2. Architecture**
## **2.1. Overview**
Each Certus-NX device contains an array of logic blocks surrounded by Programmable I/O Cells (PIC). Interspersed between the rows of logic blocks are rows of sysMEM Embedded Block RAM (EBR) and rows of sysDSP Digital Signal Processing blocks, as shown in Figure 2.1. The LFD2NX-40 devices have two rows of DSP blocks and contain three rows of sysMEM EBR blocks. In addition, LFD2NX-40 devices include two Large SRAM blocks. The sysMEM EBR blocks are large, dedicated 18 kb fast memory blocks and have built-in ECC and FIFO support. Each sysMEM block can be configured to a single, pseudo dual or true dual port memory in a variety of depths and widths as RAM or ROM. Each DSP block supports a variety of multiplier and adder configurations with one 108-bit or two 54-bit accumulators supported, which are the building blocks for complex signal processing capabilities.
Each PIC block encompasses two PIO (PIO pairs) with their respective sysI/O buffers. The sysI/O buffers of the CertusNX devices are arranged in seven banks allowing the implementation of a wide variety of I/O standards. The Wide Range (WR) I/O banks that are located on the top, left and right sides of the device provide flexible ranges of general purpose I/O configurations up to 3.3 V VCCIO. The banks located on the bottom side of the device are dedicated to High Performance (HP) interfaces such as LVDS, DDR3, LPDDR2, and LPDDR3 supporting up to 1.8 V VCCIO.
The Programmable Functional Unit (PFU) contains the building blocks for logic, arithmetic, RAM and ROM functions. The PFU block is optimized for flexibility, allowing complex designs to be implemented quickly and efficiently. Logic Blocks are arranged in a two-dimensional array. The registers in the PFU and sysI/O blocks in Certus-NX devices can be configured to be SET or RESET. After power up and device configuration, it enters into user mode with these registers SET/RESET according to the user design, allowing the device to power up in a known state for predictable system function.
In addition, Certus-NX devices provide various system level hard IP functional and interface blocks such as PCIe (LFD2NX-40 only), I[2] C, SGMII/CDR, and ADC blocks. The PCIe hard IP supports PCIe Generation 2.0. Certus-NX devices also provide security features to help protect user designs and deliver more robust reliability by offering enhanced frame-based SED/SEC functions.
Other blocks provided include PLLs, DLLs, and configuration functions. The PLL and DLL blocks are located at the corners of each device. Certus-NX devices also include the Lattice Memory Mapped Interface (LMMI) which is a Lattice standard to support simple read and write operations to control internal IP.
Every device in the family has a JTAG port. This family also provides an on-chip oscillator and soft error detect capability. The Certus-NX devices use 1.0 V as their core voltage.

## **2.2. PFU Blocks**
The core of the Certus-NX device consists of PFU blocks. Each PFU block consists of four interconnected slices numbered 0–3 as shown in Figure 2.3. Each slice contains two LUTs. All the interconnections to and from PFU blocks are from routing.
The PFU block can be used to perform Logical, Arithmetic, RAM or ROM functions. Table 2.1 shows the functions each slice can perform in either Distributed SRAM or non-distributed SRAM modes.

**Figure 2.3. PFU Diagram**
## **2.2.1. Slice**
Each slice contains two LUT4s feeding two registers. In Distributed SRAM mode, Slice 0 and Slice 1 are configured as distributed memory and Slice 2 is not available as it is used to support Slice 0 and Slice 1, while Slice 3 is available as Logic or ROM. Table 2.1 shows the capability of the slices along with the operation modes they enable. In addition, each Slice contains logic that allows the LUTs to be combined to perform a LUT5 function. There is control logic to perform set/reset functions (programmable as synchronous/asynchronous), clock select, chip-select, and wider RAM/ROM functions.
**Table 2.1. Resources and Modes Available per Slice**
|**Slice**|**PFU(Used as Distributed SRAM)**|**PFU(Used as Distributed SRAM)**|**PFU(Not used as Distributed SRAM)**|**PFU(Not used as Distributed SRAM)**|

|Slice 3|2 LUT4s and 2 Registers|Logic, Ripple, ROM|2 LUT4s and 2 Registers|Logic, Ripple, ROM|
Figure 2.4 shows an overview of the internal logic of the slice. The registers in the slice can be configured for positive or negative edge clocking.
Each slice has 17 input signals: 16 signals from routing and one from the carry-chain (from the adjacent slice or PFU). Three of them are used for FF control and shared between two slices (0/1 or 2/3). There are five outputs: four to routing and one to carry-chain (to the adjacent PFU). Table 2.2 and Figure 2.4 list the signals associated with all the slices. Figure 2.5 shows the slice signals that support a LUT5 or two LUT5 functions. F0 can be configured to have a LUT4 or LUT5 output while F1 is for a LUT4 output.

## **2.2.2. Modes of Operation**
Slices 0-2 have up to four potential modes of operation: Logic, Ripple, RAM and ROM. Slice 3 is not needed for RAM mode, it can be used in Logic, Ripple, or ROM modes.
## **2.2.2.1. Logic Mode**
In this mode, the LUTs in each slice are configured as 4-input combinatorial lookup tables. A LUT4 can have 16 possible input combinations. Any four input logic functions can be generated by programming this lookup table. Since there are two LUT4s per slice, a LUT5 can be constructed within one slice.
## **2.2.2.2. Ripple Mode**
Ripple mode supports the efficient implementation of small arithmetic functions. In ripple mode, the following functions can be implemented by each slice:
- Addition 2-bit
- Subtraction 2-bit
- Add/Subtract 2-bit using dynamic control
- Up counter 2-bit
- Down counter 2-bit
- Up/Down counter with asynchronous clear 2-bit using dynamic control
- Up/Down counter with preload (sync) 2-bit using dynamic control
- Comparator functions of A and B inputs 2-bit
- A greater-than-or-equal-to B
- A not-equal-to B
- A less-than-or-equal-to B
- Up/Down counter with A greater-than-or-equal-to B comparator 2-bit using dynamic control
- Up/Down counter with A less-than-or-equal-to B comparator 2-bit using dynamic control
- Multiplier support Ai×Bj+1 + Ai+1×Bj in one logic cell with 2 logic cells per slice
- Serial divider 2-bit mantissa, shift 1bit/cycle
- Serial multiplier 2-bit, shift 1bit/cycle or 2bit/cycle
Ripple Mode includes an optional configuration that performs arithmetic using fast carry chain methods. In this configuration (also referred to as CCU2 mode) two additional signals, Carry Generate and Carry Propagate, are generated on a per slice basis to allow fast arithmetic functions to be constructed by concatenating Slices.
## **2.2.2.3. RAM Mode**
In this mode, a 16 × 4-bit distributed single or pseudo dual port RAM can be constructed in one PFU using each LUT block in Slice 0 and Slice 1 as a 16 × 2-bit memory in each slice. Slice 2 is used to provide memory address and control signals. The Certus-NX devices support distributed memory initialization.
The Lattice design tools support the creation of a variety of different sized memories. Where appropriate, the software constructs these using distributed memory primitives that represent the capabilities of the PFU. Table 2.3 lists the number of slices required to implement different distributed RAM primitives. For more information about using RAM in Certus-NX devices, refer to Memory Usage Guide for Nexus Platform (FPGA-TN-02094).
**Table 2.3. Number of Slices Required to Implement Distributed RAM**
||**SPR1 16 × 4**|**PDPR1 16 × 4**|
|---|---|---|
|Number of slices|3|3|
**Note** :
1. SPR = Single Port RAM, PDPR = Pseudo Dual Port RAM
## **2.2.2.4. ROM Mode**
ROM mode uses the LUT logic; hence, Slice 0 through Slice 3 can be used in ROM mode. Preloading is accomplished through the programming interface during PFU configuration.
For more information, refer to Memory Usage Guide for Nexus Platform (FPGA-TN-02094).

**Certus-NX Family Data Sheet**
## **2.3. Routing**
There are many resources provided in the Certus-NX devices to route signals individually or as busses with related control signals. The routing resources consist of switching circuitry, buffers, and metal interconnect (routing) segments.
The Certus-NX family has an enhanced routing architecture that produces a compact design. The Radiant software tool takes the output of the synthesis tool and places and routes the design.
## **2.4. Clocking Structure**
The Certus-NX clocking structure consists of clock synthesis blocks (PLLs), balanced clock tree networks (PCLK & ECLK), and efficient clock logic modules: Clock Dividers (PCLKDIV and ECLKDIV), Dynamic Clock Selection (DCS), Dynamic Clock Control (DCC), and DDRDLLs. Each of these functions is described as follows.
## **2.4.1. Global PLL**
The Global PLLs (GPLL) provide the ability to synthesize clock frequencies. The devices in the Certus-NX family support two or three full-featured General Purpose GPLLs. The architecture of the GPLL is shown in Figure 2.6. A description of the GPLL functionality follows.
REFCLK is the reference frequency input to the PLL and its source can come from external CLK inputs or from internal routing. The CLKI input feeds into the input Clock Divider block.
CLKFB is the feedback signal to the GPLL which can come from a path internal to the PLL or from FPGA routing. The feedback divider is used to multiply the reference frequency and thus synthesize a higher or lower frequency clock output.
The PLL has six clock outputs CLKOP, CLKOS, CLKOS2, CLKOS3, CLKOS4, and CLKOS5. Each output has its own output divider, thus allowing the GPLL to generate different frequencies for each output. The output dividers can have a value from 1 to 128. Each GPLL output can be used to drive the primary clock or edge clock networks.
The setup and hold times of the device can be improved by programming a phase shift into the output clocks which advances or delays the output clock with reference to the un-shifted output clock. This phase shift can be either programmed during configuration or can be adjusted dynamically using the DIRSEL, DIR, DYNROTATE, and LOADREG ports.
The LOCK signal is asserted when the GPLL determines it has achieved lock and de-asserted if a loss of lock is detected. The lock signal is asynchronous to the PLL clock outputs.

For more details on the PLL, the user can refer to the sysCLOCK PLL Design and Usage Guide for Nexus Platform (FPGATN-02095).
## **2.4.2. Clock Distribution Network**
There are two main clock distribution networks for any member of the Certus-NX product family, namely Primary Clock (PCLK) and Edge Clock (ECLK). These clock networks can be driven from many different sources, such as Clock Pins, PLL outputs, DLLDEL outputs, Clock Divider outputs, SerDes/PCS clocks, and user logic. There are Clock Divider blocks (ECLKDIV and PCLKDIV) to provide a slower clock from these clock sources.
Certus-NX supports glitchless Dynamic Clock Control (DCC) for the PCLK Clock to save dynamic power. There are also Dynamic Clock Selection logic to allow glitchless selection between two clocks for the PCLK network (DCS).
An Overview of the Clocking Network is shown in Figure 2.7 for the Certus-NX device. The shaded blocks (PCIe and upper left PLL) are not available in the 17k Logic Cell device.

## **2.4.3. Primary Clocks**
The Certus-NX device family provides low-skew, high fan-out clock distribution to all synchronous elements in the FPGA fabric through the Primary Clock Network. The Certus-NX PCLK clock network is a balanced clock structure which is designed to minimize the clock skew across all destinations in the FPGA core.
The primary clock network is divided into two clock domains depending on the device density. Each of these domains has 16 clocks that can be distributed to the fabric in the domain.
The Lattice Radiant software can automatically route each clock to one of the domains up to a maximum of 16 clocks per domain. The user can change how the clocks are routed by specifying a preference in the Lattice Radiant software to locate the clock to a specific domain. The Certus-NX device provides the user with a maximum of 64 unique clock input sources that can be routed to the primary Clock network.
Primary clock sources are:
- Dedicated clock input pins
- PLL outputs
- PCLKDIV, ECLKDIV outputs
- Internal FPGA fabric entries (with minimum general routing)
- SGMII-CDR, PCIe clocks
- OSC clock
These sources are routed to each of four clock switches called a Mid Mux (LMID, RMID, TMID, BMID). The outputs of the Mid MUX are routed to the center of the FPGA where additional clock switches (DSC_CMUX) are used to route the primary clock sources to primary clock distribution to the Certus-NX fabric. These routing muxs are shown in Figure 2.7. There are potentially 64 unique clock domains that can be used in the largest Certus-NX Device. For more information about the primary clock tree and connections, refer to sysCLOCK PLL Design and Usage Guide for Nexus Platform (FPGA-TN-02095).

**Certus-NX Family Data Sheet**
## **2.4.4. Edge Clock**
Certus-NX FPGAs have a number of high-speed edge clocks that are intended for use with the PIO in the implementation of high-speed interfaces. There are four (4) ECLK networks per bank I/O on the Bottom side of the device. The Edge clock network is powered by a separate power domain (to reduce power noise injection from the core and reduce overall noise induced jitter) while controlled by the same logic that gates the FPGA core and PCLK domains for power management.
Each Edge Clock can be sourced from the following:
- Dedicated PIO Clock input pins (PCLK)
- DLLDEL output (PIO Clock delayed by 90°)
- PLL outputs (CLKOP, CLKOS, CLKOS2, CLKOS3, CLKOS4, and CLKOS5)
- Internal Nodes
Figure 2.8 illustrates the various ECLK sources. Bank 3 is shown in the example. Bank 4 and Bank 5 are similar.

**Figure 2.8. Edge Clock Sources per Bank**
The edge clocks have low injection delay and low skew. They are typically used for DDR Memory or Generic DDR interfaces. For detailed information on Edge Clock connections, refer to sysCLOCK PLL Design and Usage Guide for Nexus Platform (FPGA-TN-02095).
## **2.4.5. Clock Dividers**
The Certus-NX devices have two distinct types of clock divider, Primary and Edge. There are from one (1) to eight (8) Primary Clock Dividers (PCLKDIV) and which are located in the DCS_CMUX block(s) at the center of the device. There are twelve (12) ECLKDIV dividers per device, locate near the bottom high-speed I/O banks.
The PCLKDIV supports ÷2, ÷4, ÷8, ÷16, ÷32, ÷64, ÷128, and ÷1 (bypass) operation. The PCLKDIV is fed from a DCSMUX within the DCS_CMUX block. The clock divider output drives one input of the DCS Dynamic Clock Select within the DSC_CMUX block. The Reset (RST) control signal is asynchronous and forces all outputs to low. The divider output starts at next cycle after the reset is synchronously released. The PCLKDIV is shown in context in Figure 2.9.
The ECLKDIV is intended to generate a slower-speed system clock from a high-speed edge clock. The block operates in a ÷2, ÷3.5, ÷4, or ÷5 mode and maintains a known phase relationship between the divided down clock and the highspeed clock based on the release of its reset signal. The ECLKDIV can be fed from selected PLL outputs, external primary clock pins (with or without DLLDEL Delay) or from routing. The clock divider outputs feed into the Bottom Mid-mux (BMID). The Reset (RST) control signal is asynchronous and forces all outputs to low. The divider output starts at next cycle after the reset is synchronously released.
The ECLKDIV block is shown in context in Figure 2.8. For further information on clock dividers, refer to sysCLOCK PLL Design and Usage Guide for Nexus Platform (FPGA-TN-02095).

**Certus-NX Family Data Sheet**
## **2.4.6. Clock Center Multiplexer Blocks**
All clock sources are selected and combined for primary clock routing through the Dynamic Clock Selector Center Multiplexer logic (DCS_CMUX). There are one (1) or two (2) DCS_CMUX blocks per device. Each DCS_CMUX block contains 2 DCSMUX blocks, 1 PCLKDIV, 1 DCS block, and 1 or 2 CMUX blocks. See Figure 2.9 for a representative DCS_CMUX block diagram.
The heart of the DCS_CMUX is the Center Multiplexer (CMUX) block. It can accept up to 64 input clock sources (Midmuxes (RMID, LMID, TMIC, BMID) and DCC) and to drive up to 16 primary clock trunk lines.
Up to two (2) clock inputs to the DCS_CMUX can be routed through a Dynamic Clock Select block then routed to the CMUX. One (1) input to the DCS can be optionally divided by the Primary Clock Divider (PCLKDIV). For more information about the DCS_CMUX, refer to sysCLOCK PLL Design and Usage Guide for Nexus Platform (FPGA-TN-02095).

**Figure 2.9. DCS_CMUX Diagram**
## **2.4.7. Dynamic Clock Select**
The Dynamic Clock Select (DCS) is a smart multiplexer function available in the primary clock routing. It switches between two independent input clock sources. Depending on the operational mode, it switches between two (2) independent input clock sources either with or without any glitches. This is achieved regardless of when the select signal is toggled. Both input clocks must be running to achieve a functioning glitchless DCS output clock, but running clocks are not required when used as a non-glitchless normal clock multiplexer.
There are one (1) or two (2) DCS blocks per device that feed all clock domains. The DCS blocks are located in the DCS_MUX block. The inputs to the DCS blocks come from MIDMUX outputs and user logic clocks via DCC elements. The DCS elements are located at the center of the PLC array core. The output of the DCS is connected to the inputs of Primary Clock Center MUXs (CMUX).
Figure 2.10 shows the timing waveforms of the default DCS operating mode. The DCS block can be programmed to other modes. For more information about the DCS, refer to sysCLOCK PLL Design and Usage Guide for Nexus Platform (FPGA-TN-02095).

## **2.4.8. Dynamic Clock Control**
The Dynamic Clock Control (DCC), Domain Clock enable/disable feature allows internal logic control of the domain primary clock network. When a clock network is disabled, the clock signal is static and does not toggle. All the logic fed by that clock also does not toggle, reducing the overall power consumption of the device. The disable function is glitchless, and does not increase the clock latency to the primary clock network.
Four additional DCC elements control the clock inputs from the Certus-NX domain logic to the Center MUX elements (DSC_CMUX).
This DCC controls the clock sources from the Primary CLOCK MIDMUX before they are fed to the Primary Center MUXs that drive the domain clock network. For more information about the DCC, refer to sysCLOCK PLL Design and Usage Guide for Nexus Platform (FPGA-TN-02095).
## **2.4.9. DDRDLL**
Certus-NX has two identical DDRDLL blocks, located in the lower left and lower right corners of the device. Each DDRDLL (master DLL block) can generate a 9 bit phase shift value corresponding to a 90-degree phase shift of the reference clock input and provide this value to every DQS block and DLLDEL slave delay element. The reference clock can be either from a PLL or an input pin. The DQSBUF uses this value to control the delay of the DQS inputs from a DDR memory interface to achieve a 90-degree shift in order to clock DQ inputs at the center of the data eye.
- The value is also sent to another slave DLL, DLLDEL, that takes a primary clock input and generates a 90-degree shifted clock output to drive the clocking structure. This is useful in an edge-aligned Generic DDR interface, where 90-degree clocking needs to be created. Not all primary clock inputs have associated DLLDEL control. Figure 2.11 shows DDRDLL connectivity to a DLLDEL block (connectivity to DQSBUF blocks is similar).

## **2.5. SGMII TX/RX**
The Certus-NX device utilizes different components/resources for the transmit and receive paths of Serial Gigabit Media Independent Interface (SGMII). For the SGMII transmit path, Generic DDR I/O with X5 gearing are used. For more information, refer to the GDDRX5_TX.ECLK.Aligned interface section in the Certus-NX High-Speed I/O Interface (FPGA-TN-02216).
For the SGMII receive path, one of the two available hardened CDR (Clock and Data Recovery) Components can be used. There are three main blocks in each CDR: the CDR, deserializer, and FIFO. Each CDR features two loops. The first loop is locked to the reference clock. Once locked, the loop switches to the data path loop where the CDR tracks the data signals to generate the correcting signals that needed to achieve and maintain phase lock with the data. The data is then passed through a deserializer which deserializes the data to 10-bit parallel data. The 10-bit parallel data is then sent to the FIFO bridge, which allows the CDR to interface with the rest of the FPGA.
Figure 2.13 shows a block diagram of the SGMII CDR IP.

The two hardened blocks are located at the bottom left of the chip and uses the high speed I/O Bank 5 for the differential pair input. It is recommended that the reference clock should be entered through a GPIO that has connection to the PLL on the lower left corner as well.
For more information on how to implement the hardened CDR for the SGMII solution, refer to the SGMII and Gb Ethernet PCS IP Core (FPGA-IPUG-02077).

## **2.6. sysMEM Memory**
The Certus-NX devices contain a number of sysMEM Embedded Block RAM (EBR). The EBR consists of an 18 kb RAM with memory core, dedicated input registers and output registers as well as optional pipeline registers at the outputs. Each EBR includes functionality to support true dual-port, pseudo dual-port, single-port RAM, ROM and built in FIFO. In Certus-NX, unused EBR blocks is powered down to minimize power consumption.
## **2.6.1. sysMEM Memory Block**
The sysMEM block can implement single port, dual port or pseudo dual port memories. Each block can be used in a variety of depths and widths as listed in Table 2.4. FIFOs can be implemented using the built in read and write address counters and programmable full, almost full, empty and almost empty flags. The EBR block facilitates parity checking by supporting an optional parity bit for each data byte. EBR blocks provide byte-enable support for configurations with 18bit and 36-bit data widths. For more information, refer to Memory Usage Guide for Nexus Platform (FPGA-TN-02094). EBR also provides a build in ECC engine, which is available in Commercial/Industrial –8 and –9 speed grades and Automotive –7 speed grade. The ECC engine supports a write data width of 32 bits and it can be cascaded for larger data widths such as x64. The ECC parity generator creates and stores parity data for each 32-bit word written. When a read operation is performed, it compares the data with its associated parity data and report back if any Single Event Upset (SEU) event has disturbed the data. Any single bit data disturb is automatically corrected at the data output. In addition, two dedicated error flags indicate if a single-bit or two-bit error has occurred.

## **2.6.2. Bus Size Matching**
All the multi-port memory modes support different widths on each of the ports (except ECC mode which only supports a write data width of 32 bits). The RAM bits are mapped LSB word 0 to MSB word 0, LSB word 1 to MSB word 1, and so on. Although the word size and number of words for each port varies, this mapping scheme applies to each port.
## **2.6.3. RAM Initialization and ROM Operation**
If desired, the contents of the RAM can be pre-loaded during device configuration. By preloading the RAM block during the chip configuration cycle and disabling the write controls, the sysMEM block can also be utilized as a ROM.
## **2.6.4. Memory Cascading**
Larger and deeper blocks of RAM can be created using EBR sysMEM Blocks. Typically, the Lattice design tools cascade memory transparently, based on specific design inputs.
## **2.6.5. Single, Dual and Pseudo-Dual Port Modes**
In all the sysMEM RAM modes, the input data and address for the ports are registered at the input of the memory array. The output data of the memory is optionally registered at the output.
## **2.6.6. Memory Output Reset**
The EBR utilizes latches at the A and B output ports. These latches can be reset asynchronously or synchronously. RSTA and RSTB are local signals, which reset the output latches associated with Port A and Port B, respectively. The Global Reset (GSRN) signal can reset both ports. The output data latches and associated resets for both ports are as shown in Figure 2.14. The optional Pipeline Registers at the outputs of both ports are also reset in the same way.

## **2.7. Large RAM**
The Certus-NX device includes additional memory resources in the form of Large Random-Access Memory (LRAM) blocks.
The LRAM is designed to work as Single-Port RAM, Dual-Port RAM, Pseudo Dual-Port RAM, and ROM memories. It is meant to function as additional memory resources for the user beyond what is available in the EBR and PFU.
Each individual Large RAM block contains 0.5 Mbits or megabits of memory, and has a programmable data width of up to 32 bits. Cascading Large RAM blocks allows data widths of up to 64 bits. Additionally, there is the ability to use either Error Correction Coding (ECC) or byte enable.
## **2.8. sysDSP**
The Certus-NX family provides an enhanced sysDSP architecture, making it ideally suited for low-cost, highperformance Digital Signal Processing (DSP) applications. Typical functions used in these applications are Finite Impulse Response (FIR) filters, Fast Fourier Transforms (FFT) functions, Correlators, Reed-Solomon/Turbo/Convolution encoders, and decoders. These complex signal processing functions use similar building blocks such as multiply-adders and multiply-accumulators.
## **2.8.1. sysDSP Approach Compared to General DSP**
Conventional general-purpose DSP chips typically contain one to four (Multiply and Accumulate) MAC units with fixed data-width multipliers; this leads to limited parallelism and limited throughput. Their throughput is increased by higher clock speeds. In the Certus-NX device family, there are many DSP blocks that can be used to support different data widths. This allows the user to use highly parallel implementations of DSP functions. The user can optimize DSP performance versus area by choosing appropriate levels of parallelism. Figure 2.15 compares the fully serial implementation to the mixed parallel and serial implementation.

## **2.8.2. sysDSP Architecture Features**
The Certus-NX sysDSP block contains two sysDSP slices. The Certus-NX sysDSP Slice has been significantly enhanced to provide functions needed for advanced processing applications. These enhancements provide improved flexibility and resource utilization.
The Certus-NX sysDSP block (two sysDSP slices) supports many functions that include the following:
- Symmetry support. The primary target application is wireless. 1D Symmetry is useful for many applications that use FIR filters when their coefficients have symmetry or asymmetry characteristics. The main motivation for using 1D symmetry is cost/size optimization. The expected size reduction is up to 2x.
- Odd Mode – Filter with Odd number of taps
- Even Mode – Filter with Even number of taps
- Two-dimensional (2D) Symmetry Mode – Supports 2D filters for mainly video applications
- Dual-multiplier architecture. Lower accumulator overhead to half and the latency to half compared to single multiplier architecture.
- Fully cascadable DSP across slices. Support for symmetric, asymmetric and non-symmetric filters.
- Multiply (36 × 36, two 18 × 36, four 18 × 18, or eight 9 × 9)
- Multiply Accumulate (supports one 18 × 36 multiplier result accumulation, two 18 × 18 multiplier result accumulation or four 9 × 9 multiplier result accumulation)
- Two Multiplies feeding one Accumulate per cycle for increased processing with lower latency (two 18 × 18 Multiplies feed into an accumulator that can accumulate up to 54 bits)
- Pipeline registers
- 1D Symmetry support. The coefficients of FIR filters have symmetry or negative symmetry characteristics.
- Odd Mode – Filter with Odd number of taps
- Even Mode – Filter with Even number of taps
- 2D Symmetry support. The coefficients of 2D FIR filters have symmetry or negative symmetry characteristics.
- 3 × 3 and 3 × 5 – Internal DSP Slice support
- 5 × 5 and larger size 2D blocks – Semi internal DSP Slice support

## **2.9. Programmable I/O (PIO)**
The programmable logic associated with an I/O is called a PIO. The individual PIO are connected to their respective sysI/O buffers and pads. In Certus-NX devices, the PIO are assembled into groups of two PIO cells called a Programmable I/O Cell or PIC. The PICs are placed on all four sides of the device.
On all the Certus-NX devices, two adjacent PIO can be combined to provide a complementary output driver pair.
## **2.10. Programmable I/O Cell (PIC)**
The programmable I/O cells (PIC) provides I/O function and necessary gearing logic associated with PIO. Certus-NX consists of base PIC and gearing PIC.
Base PICs contain three blocks: an input register block, output register block, and tri-state register block. These blocks contain registers for operating in a variety of modes along with the necessary clock and selection logic. Base PICs cover the top and left/right bank. Gearing PICs contain gearing logic and edge monitor used for locating the center of data window. Gearing PICs cover the bottom banks to support DDR operation.

## **2.10.1. Input Register Block**
The input register blocks for the PIO on all edges contain delay elements and registers that can be used to condition high-speed interface signals before they are passed to the device core. In addition, the input register blocks for the PIO on the bottom edges include built-in FIFO logic to interface to DDR and LPDDR memory.
The Input register block on the bottom side includes gearing logic and registers to implement IDDRX1, IDDRX2, IDDRX4, IDDRX5 gearing functions. With two PICs sharing the DDR register path, it can also implement the IDDRX71 function used for 7:1 LVDS interfaces. It uses three sets of registers – shift, update, and transfer to implement gearing and the clock domain transfer. The first stage registers sample the high-speed input data by the high-speed edge clock on its rising and falling edges. The second stage registers perform data alignment based on the control signals. The third stage pipeline registers pass the data to the device core synchronized to the low-speed system clock. For more information on gearing function, refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216).
## **2.10.2.1. Input FIFO**
The Certus-NX PIO has a dedicated input FIFO per single-ended pin for input data register for DDR Memory interfaces. The FIFO resides before the gearing logic. It transfers data from DQS domain to continuous ECLK domain. On the Write side of the FIFO, it is clocked by DQS clock, which is the delayed version of the DQS Strobe signal from DDR memory. On the Read side of FIFO, it is clocked by ECLK. ECLK may be any high-speed clock with identical frequency as DQS (the frequency of the memory chip). Each DQS group has one FIFO control block. It distributes FIFO read/write pointers to every PIC in same DQS group. DQS Grouping and the DQS Control Block is described in DDR Memory Support section.

## **2.11. Tri-state Register Block**
The tri-state register block registers tri-state control signals from the core of the device before they are passed to the sysI/O buffers. The block contains a register for SDR operation. In SDR, the TD input feeds one of the flip-flops that then feeds the output. In DDR, operations used mainly for DDR memory interfaces can be implemented on the bottom side of the device. Here, two inputs feed the tri-state registers clocked by both ECLK and SCLK.
Figure 2.23 and Figure 2.24 show the Tri-state Register Block functions on the device. For a detailed description of the tri-state register block modes and usage, refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216).

## **2.12. DDR Memory Support**
## **2.12.1. DQS Grouping for DDR Memory**
Certain PICs have additional circuitry to allow the implementation of high-speed source synchronous and DDR3/DDR3L, LPDDR2 or LPDDR3 memory interfaces. The support varies by the edge of the device as detailed below.
The Bottom bank PIC have fully functional elements supporting DDR3/DDR3L, LPDDR2, or LPDDR3 memory interfaces. Every 16 PIO on the bottom side are grouped into one DQS group, as shown in Figure 2.25. Within each DQS group, there are two pre-placed pins for DQS and DQS# signals. The rest of the pins in the DQS group can be used as DQ signals and DM signal. The number of pins in each DQS group bonded out is package dependent. DQS groups with less than 11 pins bonded out can only be used for LPDDR2/3 Command/ Address busses. In DQS groups with more than 11 pins bonded out, up to two pre-defined pins are assigned to be used as virtual VCCIO, by driving them high to make extra connections to the VCCIO power supply. These soft connections to VCCIO help reduce SSO noise. For details, refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216).

## **2.12.2. DLL Calibrated DQS Delay and Control Block (DQSBUF)**
To support DDR memory interfaces (DDR3/DDR3L, LPDDR2/3), the DQS strobe signal from the memory must be used to capture the data (DQ) in the PIC registers during memory reads. This signal is output from the DDR memory device aligned to data transitions and must be time shifted before it can be used to capture data in the PIC. This time shift is achieved by using the DQSBUF programmable delay line in the DQS Delay Block (DQS read circuit). The DQSBUF is implemented as a slave delay line and works in conjunction with a master DDRDLL.
This block also includes a slave delay line to generate delayed clocks used during writes to generate DQ and DQS with correct phases within one DQS group. There is a third delay line inside this block used to provide write leveling for DDR write if needed.
Each of the read and write side delays can be dynamically shifted using margin control signals from the core logic.
The FIFO Control Block include here generates the Read and Write Pointers for the FIFO inside the Input Register Block. These pointers are generated to control the DQS to ECLK domain crossing using the FIFO module.

## **2.13. sysI/O Buffer**
Each I/O is associated with a flexible buffer referred to as a sysI/O buffer. These buffers are arranged around the periphery of the device in groups referred to as banks. The sysI/O buffers allow the user to implement a wide variety of standards that are found in today’s systems including LVDS, HSUL, SSTL Class I and II, LVCMOS, and LVTTL.
The Certus-NX family contains multiple Programmable I/O Cell (PIC) blocks. Each PIC contains two Programmable I/O, PIOA and PIOB. Each PIO includes a sysI/O buffer and I/O logic. Two adjacent PIO can be joined to provide a differential I/O pair referred to as True and Comp, where True Pad is associated with the positive side of the differential I/O, and the complement with the negative.
The top, left, and right side banks support I/O standards from 3.3 V to 1.0 V while the bottom supports I/O standards from 1.8 V to 1.0 V. Every pair of I/O on the bottom bank also have a true LVDS and SLVS Tx Driver. In addition, the bottom bank supports single-ended input termination. Both static and dynamic termination are supported. Dynamic termination is used to support the DDR/LPDDR interface standards. For more information about DDR implementation in I/O Logic and DDR memory interface support, refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216).
## **2.13.1. Supported sysI/O Standards**
Certus-NX sysI/O buffers supports both single-ended differential and differential standards. Single-ended standards can be further subdivided into internally ratioed standards such as LVCMOS, LVTTL, and externally referenced standards such as HSUL and SSTL. The buffers support the LVTTL, LVCMOS 1.0 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V standards. Differential standards supported include LVDS, SLVS, differential LVCMOS, differential SSTL, and differential HSUL. For better support of video standards, subLVDS is also supported. Table 2.10 and Table 2.11 provide a list of sysI/O standards supported in Certus-NX devices.

## **2.13.2.1. Typical sysI/O Behavior During Power-up**
The internal Power-On-Reset (POR) signal is deactivated when VCC and VCCAUX have reached satisfactory levels. After the POR signal is deactivated, the FPGA core logic becomes active. It is the user’s responsibility to ensure that all other VCCIO banks are active with valid input logic levels to properly control the output logic states of all the I/O banks that are critical to the application. For more information about controlling the output logic state with valid input logic levels during power-up in Certus-NX devices, see the list of technical documentation in References section.
VCC and VCCAUX supply the power to the FPGA core fabric, whereas VCCIO supplies power to the I/O buffers. In order to simplify the system design while providing consistent and predictable I/O behavior, it is recommended that the I/O buffers be powered-up prior to the FPGA core fabric. For the different power supply voltage levels by the I/O banks, refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216) for detailed information.
## **2.13.2.2. VREF1 and VREF2**
Bank 3, Bank 4, and Bank 5 can support two separate VREF input voltages, VREF1, and VREF2. To assign a VREF driver, use IO_Type = VREF1_DRIVER or VREF2_DRIVER. To assign VREF to a buffer, use VREF1_LOAD or VREF2_LOAD.
## **2.13.2.3. sysI/O Standards Supported by I/O Bank**
All banks can support multiple I/O standards under the VCCIO rules discussed above. Table 2.12 and Table 2.13 summarize the I/O standards supported on various sides of the Certus-NX device.

## **2.13.2.4. Hot Socketing**
The Certus-NX devices have been carefully designed to ensure predictable behavior during power-up and power-down. During power-up and power-down sequences, the I/O remain in tri-state until the power supply voltage is high enough to ensure reliable operation. In addition, leakage into I/O pins is controlled within specified limits. Bank 0, Bank 1, Bank 2, Bank 6, and Bank 7 are fully hot hot socketable. Bank 3, Bank 4, and Bank 5 do not support hot socketing.
## **2.13.3. sysI/O Buffer Configurations**
This section describes the various sysI/O features available on the Certus-NX device. Refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216) for detailed information.

**Certus-NX Family Data Sheet**
## **2.14. Analog Interface**
The Certus-NX family can provide an analog interface consisting of two Analog to Digital Converters (ADC), three continuous time comparators, and an internal junction temperature monitoring diode. This feature is available in Commercial/Industrial –8 and –9 speed grades and Automotive –7 speed grade. The two ADCs can operate either sequentially or simultaneously.
## **2.14.1. Analog to Digital Converters**
The Analog to Digital Convertor is a 12-bit, 1 MSPS SAR (Successive Approximation Register) architecture converter. The ADC supports both continuous and single shot conversion modes.
The ADC input is selected among pre-selected GPIO input pairs, dedicated analog input pair, the internal junction temperature sensing diode and internal voltage rails. The input signal can be converted in either uni-polar or bi-polar mode.
The reference voltage is selectable between the 1.2 V internal reference generator and an external reference. The ADC can convert up to a 1.8 V input signal with a 1.8 V external reference voltage. The ADC has an auto-calibration function which calibrates the gain and offset.
## **2.14.2. Continuous Time Comparators**
The continuous-time comparator can be used to monitor a dedicated input pair or a GPIO input pair. The output of the comparator is provided as continuous and latched outputs.
## **2.14.3. Internal Junction Temperature Monitoring Diode**
On-die junction temperature can be monitored using the internal junction temperature monitoring diode. The PTAT (proportional to absolute temperature) diode voltage can be monitored by the ADC to provide a digital temperature readout. Refer to ADC Usage Guide for Nexus Platform (FPGA-TN-02129) for more details.
## **2.15. IEEE 1149.1-Compliant Boundary Scan Testability**
All Certus-NX devices have boundary scan cells that are accessed through an IEEE 1149.1 compliant Test Access Port (TAP). This allows functional testing of the circuit board on which the device is mounted through a serial scan path that can access all critical logic nodes. Internal registers are linked internally, allowing test data to be shifted in and loaded directly onto test nodes, or test data to be captured and shifted out for verification. The test access port consists of dedicated I/O: TDI, TDO, TCK, and TMS. The test access port uses VCCIO1 for power supply. The test access port is supported for VCCIO1 = 1.8 V - 3.3 V.
For more information, refer to sysCONFIG User Guide for Nexus Platform (FPGA-TN-02099).

**Certus-NX Family Data Sheet**
## **2.16. Device Configuration**
All Certus-NX devices contain various ports that can be used for configuration, including a Test Access Port (TAP). The TAP supports both the IEEE Standard 1149.1 Boundary Scan specification and the IEEE Standard 1532 In-System Configuration specification. JTAG_EN is the only dedicated configuration pin _. PPROGRAMN/INITN/DONE_ are enabled by default, but can be turned into GPIO _._ The remaining sysCONFIG pins are used as dual function pins. Refer to sysCONFIG User Guide for Nexus Platform (FPGA-TN-02099) for more information about using the dual-use pins as general purpose I/O.
There are various ways to configure a Certus-NX device:
- JTAG (TAP)
- Master Serial Peripheral Interface (SPI) – to load from external SPI flash using ×1, ×2, or ×4 (QSPI) interfaces.
- Inter-Integrated Circuit Bus (I[2] C)
- Improved Inter-Integrated Circuit Bus (I3C)
- Slave SPI from a system host
- Lattice Memory Mapped Interface (LMMI), refer to sysI/O Usage Guide for Nexus Platform (FPGA-TN-02067) for details.
- JTAG, SSPI, MSPI, I[2] C, and I3C are supported for VCCIO = 1.8 V - 3.3 V
On power-up, based on the voltage level (high or low) of the PROGRAMN pin, the FPGA SRAM is configured by the appropriate sysCONFIG port. If PROGRAMN pin is _low_ , the FPGA is in the Slave configuration ports (Slave SPI, Slave I[2] C or Slave I3C) and is waiting for the correct Slave Configuration port activation key. PROGRAMN must be driven high within 50 ns of the end of transmission of the Slave Configuration port activation key, that is, the de-assertion of SCSN. If no slave port is declared active before the PROGRAMN pin is sensed HIGH, the FPGA is in Master SPI booting mode. In Master SPI booting mode, the FPGA boots from an external SPI flash. Once a configuration port is activated, it remains active throughout that configuration cycle. The IEEE 1149.1 port can be activated any time after power-up by enabling the JTAG_EN pin and sending the appropriate command through the TAP port.
## **2.16.1. Enhanced Configuration Options**
Certus-NX devices have enhanced configuration features such as:
- Early I/O release
- Bitstream decryption
- Decompression support
- Watchdog Timer support
- Dual and Multi-boot image support
Early I/O Release is a new configuration feature in which certain I/O banks are released earlier so that customer systems have minimal disruption. For more details, refer to sysCONFIG User Guide for Nexus Platform (FPGA-TN02099).
Watchdog Timer is a new configuration feature that helps the user add a programmable timer option for timeout applications.
## **2.16.2.1. Dual-Boot and Multi-Boot Image Support**
Dual-boot and multi-boot images are supported for applications requiring reliable remote updates of configuration data for the system FPGA. After the system is running with a basic configuration, a new boot image can be downloaded remotely and stored in a separate location in the configuration storage device. Any time after the update the Certus-NX devices can be re-booted from this new configuration file. If there is a problem, such as corrupt data during download or incorrect version number with this new boot image, the Certus-NX device can revert back to the original backup golden configuration and try again. This all can be done without power cycling the system. For more information, refer to sysCONFIG User Guide for Nexus Platform (FPGA-TN-02099).

**Certus-NX Family Data Sheet**
## **2.17. Single Event Upset (SEU) Handling**
Certus-NX devices are unique because the underlying technology used to build these devices is much more robust and less prone to soft errors.
Certus-NX devices have an improved, hardware implemented, Soft Error Detection (SED) circuit which can be used to detect SRAM errors so they can be corrected. There are two layers of SED implemented in Certus-NX making it more robust and reliable.
The SED hardware in Certus-NX devices is part of the Configuration block. The SED module in Certus-NX is an enhanced version as compared to the SED modules implemented in other Lattice devices. The configuration data is divided into frames so that the entire FPGA can be programmed precisely with ease. The SED hardware reads data from the FPGAs configuration memory and performs an Error Correcting Code (ECC) calculation on every frame of configuration data (see Figure 2.1). Once an error is detected, a notification is generated and SED resumes operation. For single bit errors, the corrected value is rewritten to the particular frame using ECC information. If more than one bit error is detected within one frame of configuration data, an error message is generated. Certus-NX devices also have dedicated logic to perform Cycle Redundancy Code (CRC) checks for the entire bitstream, which runs in parallel along with ECC.
After the ECC is calculated on all frames of configuration data, CRC is calculated and checked for the entire bitstream. ECC and CRC checks do not include the contents of RAMs (EBR, Large RAM, and distributed RAM).
For further information on SED support, refer to Soft Error Detection (SED)/Correction (SEC) User Guide for Nexus Platform (FPGA-TN-02076).
## **2.18. On-Chip Oscillator**
The Certus-NX device features two on board oscillators. Both Oscillators are controlled with internally generated current.
The low frequency oscillator (LFOSC) is tailored for low power operation and runs at a nominal frequency of 128 kHz. The LFOSC always runs and can be used to perform always on functions with the lowest possible power. The high frequency oscillator (HFOSC) runs at a nominal frequency of 450 MHz, but can be divided down to a range of 256 MHz to 2 MHz by user attributes.

**Certus-NX Family Data Sheet**
## **2.19. User I²C IP**
The Certus-NX device has one hard I²C interface, which can be configured either as a master (controller) or a slave (responder). The pins for the I²C interface are pre-assigned.
The interface core has the option to delay the either the input or the output data (SDA), or both, by 50 ns nominal, using dedicated on-chip delay elements. This provides an easier interface to any external I[2] C components. In addition, 50 ns glitch filters are available for both SDA and SCL.
When the interface is configured as master (controller), it can control other devices on the I[2] C bus through the preassigned pins. When the core is configured as a slave (responder), the device can provide, for example, I/O expansion to an I²C master (controller). The I²C core supports the following functionality:
- Master (controller) and slave (responder) operation
- 7-bit and 10-bit addressing
- Multi-master (controller) arbitration support
- Clock stretching
- Up to 1 MHz data transfer speed (Standard-Mode, Fast-Mode, Fast-Mode Plus)
- General Call support
- Optional receive and transmit data FIFOs with programmable sizes
- Optional 50 ns delay on input or output data (SDA), or both
- Hard-Connection and Programmable I/O Connection Support
- Programmable to a mode compliant with I3C requirements on legacy I[2] C Slave Devices.
- Fast-Mode and Fast-Mode Plus Support
- Disabled Clock Stretching
- 50 ns SCL and SDA Glitch Filters
- Programmable 7-bit Address
For further information on the User I²C, refer to I[2] C Hardened IP Usage Guide for Nexus Platform (FPGA-TN-02142).
## **2.20. Trace ID**
Each Certus-NX device contains a unique (per device) TraceID that can be used for tracking purposes or for IP security applications. The TraceID is 64 bits long. Eight out of 64 bits are user-programmable, the remaining 56 bits are factoryprogrammed. The TraceID is accessible through the SPI, I2C, or JTAG interfaces. For further information on TraceID, refer to Using TraceID (FPGA-TN-02084).
## **2.21. Density Shifting**
The Certus-NX family is designed to ensure that different density devices in the same family and in the same package have the same pinout. Furthermore, the architecture ensures a high success rate when performing design migration from lower density devices to higher density devices. In many cases, it is also possible to shift a low utilization design targeted for a high-density device to a lower density device. However, the exact details of the final resource utilization impact the likelihood of success in each case. An example is that some user I/O may become No Connects in smaller devices in the same package. Refer to the Certus-NX Pin Migration Tables and Lattice Radiant software for specific restrictions and limitations.

The hardened PCIe block can be instantiated with the primitive _PCIe_ through Lattice Radiant software however, it is not recommended to directly instantiate the PCIe primitive itself. It is highly recommended to generate the PCIe Endpoint Soft IP through the Radiant IP Catalog & IP Block Wizard instead. In Figure 2.29, the PCIe core is configured as an Endpoint using a soft IP wrapper that provides useful functions such as bridging support for bus interfaces and DMA applications. In addition to the standard Transaction Layer Packet (TLP) interface, the data interface can also be configured to be AXI4 or AHB-Lite as well. The PCIe hardened block also features a register interface for LMMI and User Configuration Space Register Interface (UCFG). The PCIe block has many registers which contain information about the current status of the PCIe block as well as the capability to dynamically switch PCIe settings. One easy way to access these registers is through the Reveal Controller Tool.
For more information about the PCIe soft IP, refer to the PCIe Endpoint IP Core document.

## **2.23. Cryptographic Engine**
The Certus-NX family of devices support several cryptographic features that helps customer secure their design. Some of the key cryptographic features include Advanced Encryption Standard (AES) encryption, Hashing Algorithms, and true random number generation (TRNG). The Certus-NX device also features bitstream encryption (AES-256), used for protecting confidential FPGA bitstream data, and bitstream authentication (using ECDSA), which maintains bitstream integrity and protects the FPGA design bitstream from copying and tampering.
The Cryptographic Engine (CRE) is the main block, which is responsible for bitstream encryption as well as authentication of the Certus-NX device. Once the bitstream is authenticated and the device is ready for user functions, the CRE is available to implement various cryptographic functions in the FPGA design. To enable specific cryptographic functions, the CRE must be configured by setting a few registers.
The Cryptographic Engine supports the below user-mode features:
- True Random Number Generator (TRNG)
- Secure Hashing Algorithm (SHA)-256 bit
- Message Authentication Codes (MACs) – HMAC
- Lattice Memory Mapped Interface (LMMI) to user logic
- High Speed Port (HSP) for FIFO-based streaming data transfer

**Notes** :
1. Single-ended input can mix into I/O Banks with VCCIO different from the standard requires due to some of these input standards use internal supply voltage source (VCC, VCCAUX) to power the input buffer, which makes them to be independent of VCCIO voltage. For more details, refer to sysI/O Usage Guide for Nexus Platform (FPGA-TN-02067). The following is a brief guideline to follow:
- a. Weak pull-up on the I/O must be set to OFF.
- b. Bank 3, Bank 4, and Bank 5 I/O can only mix into banks with VCCIO higher than or equal to the pin standard, due to clamping diode on the pin in these banks. Bank 0, Bank 1, Bank 2, Bank 6, and Bank 7 do not have this restriction.
- c. LVCMOS25 uses VCCIO supply on input buffer in Bank 0, Bank 1, Bank 2, Bank 6, and Bank 7. It can be supported with VCCIO = 3.3 V to meet the VIH and VIL requirements, but there is additional current drawn on VCCIO. Hysteresis has to be disabled when using 3.3 V supply voltage.
- d. LVCMOS15 uses VCCIO supply on input buffer in Bank 3, Bank 4, and Bank 5. It can be supported with VCCIO = 1.8 V to meet the VIH and VIL requirements, but there is additional current drawn on VCCIO.

2. Single-ended LVCMOS inputs can mixed into I/O Banks with different VCCIO, providing weak pull-up is not used. For additional information on Mixed I/O in Bank VCCIO, refer to sysI/O Usage Guide for Nexus Platform (FPGA-TN-02067) **.**
3. These inputs use differential input comparator in Bank 3, Bank 4, and Bank 5. The differential input comparator uses VCCAUXH power supply. These inputs require the VREF pin to provide the reference voltage in the Bank. Refer to sysI/O Usage Guide for Nexus Platform (FPGA-TN-02067) for details **.**
4. All differential inputs use differential input comparator in Bank 3, Bank 4, and Bank 5. The differential input comparator uses VCCAUXH power supply. There is no differential input signaling supported in Bank 0, Bank 1, Bank 2, Bank 6, and Bank 7.
5. These outputs are emulating differential output pair with single-ended output drivers with true and complement outputs driving on each of the corresponding true and complement output pair pins. The common mode voltage, VCM, is ½ × VCCIO. Refer to sysI/O Usage Guide for Nexus Platform (FPGA-TN-02067) for details **.**
6. VCCIO = 1.35 V is only supported in Bank 3, Bank 4, and Bank 5, for use with DDR3L interface in the bank. These Input and Output standards can fit into the same bank with the VCCIO = 1.35 V.
7. LVCMOS15 input uses VCCIO supply voltage. If VCCIO is 1.8 V, the DC levels for LVCMOS15 are still met, but there could be increase in input buffer current.

## **3.12. sysI/O Differential DC Electrical Characteristics**
## **3.12.1. LVDS**
LVDS input buffer on CrossLink-NX is powered by VCCAUX = 1.8 V, and protected by the bank VCCIO. Therefore, the LVDS input voltage cannot exceed the bank VCCIO voltage. LVDS output buffer is powered by the Bank VCCIO at 1.8 V.
LVDS can only be supported in Bank 3, Bank 4, and Bank 5. LVDS25 output can be emulated with LVDS25E in Bank 0, Bank 1, Bank 2, Bank 6, and Bank 7. This is described in LVDS25E (Output Only) section.

**Notes** :
1. LVDS input or output are supported in Bank 3, Bank 4, and Bank 5. LVDS input uses VCCAUX on the differential input comparator, and can be located in any VCCIO voltage bank. LVDS output uses VCCIO on the differential output driver, and can only be located in bank with VCCIO = 1.8 V.
2. VICM is depending on VID, input differential voltage, so the voltage on pin cannot exceed VINP/INM(min/max) requirements. VICM(min) = VINP/INM(min) + ½ VID, VICM(max) = VINP/INM(max) – ½ VID. Values in the table is based on minimum VID of +/– 100 mV.
3. VINP, VINM(max) must be less than or equal to VCCIO in all cases.

## **3.12.3. SubLVDS (Input Only)**
SubLVDS is a reduced-voltage form of LVDS signaling, very similar to LVDS. It is a standard used in many camera types of applications, and follow the SMIA 1.0, Part 2: CCP2 Specification. Being similar to LVDS, the Certus-NX devices can support the subLVDS input signaling with the same LVDS input buffer. The output for subLVDS is implemented in subLVDSE/subLVDSEH with a pair of LVCMOS18 output drivers (see SubLVDSE/SubLVDSEH (Output Only) section).

## **3.12.5. SLVS**
Scalable Low-Voltage Signaling (SLVS) is based on a point-to-point signaling method defined in the JEDEC JESD8-13 (SLVS-400) standard. This standard evolved from the traditional LVDS standard with smaller voltage swings and a lower common-mode voltage. The 200 mV (400 mV p-p) SLVS swing contributes to a reduction in power.
The Certus-NX devices receive SLVS differential input with the LVDS input buffer. This LVDS input buffer is design to cover wide input common mode range that can meet the SLVS input standard specified by the JEDEC standard.
**Table 3.23. SLVS Input DC Characteristics**
|**Parameter**<br>~~OS~~|**Description**<br>~~OS~~|**Test Conditions**<br>~~OS~~|**Min**<br>~~OS~~|**Typ**<br>~~OS~~|**Max**<br>~~OS~~|**Unit**<br>~~OS~~|

The SLVS output on the Certus-NX device is supported with the LVDS drivers found in Bank 3, Bank 4, and Bank 5. The LVDS driver on the Certus-NX device is a current controlled driver. It can be configured as LVDS driver, or configured with the 100 Ω differential termination with center-tap set to VOCM at 200 mV. This means the differential output driver can be placed into bank with VCCIO = 1.2 V, 1.5 V, or 1.8 V, even if it is powered by VCCIO.

## **3.12.6. Soft MIPI D-PHY**
When Soft D-PHY is implemented inside the FPGA logic, the I/O interface needs to use sysI/O buffers to connect to external D-PHY pins.
The Certus-NX sysI/O provides support for SLVS, as described in SLVS section, plus the LVCMOS12 input/output buffers together to support the High Speed (HS) and Low Power (LP) mode as defined in MIPI Alliance Specification for D-PHY. To support MIPI D-PHY with SLVS (LVDS) and LVCMOS12, the bank VCCIO cannot be set to 1.5 V or 1.8 V. It must connect to 1.2 V, or 1.1 V.
All other DC parameters are the same as listed in SLVS section. DC parameters for the LP driver and receiver are the same as listed in LVCMOS12.

**Notes** :
1. Maximum I/O speed is the maximum switching rate of the I/O operating within the guidelines of the defining standard. The actual interface speed performance using the I/O also depends on other factors, such as internal and external timing.
2. These numbers are characterized but not test on every device.
3. Performance is specified in MHz, as defined in clock rate when the sysI/O is used as pin. For data rate performance, this can be converted to Mbps, which equals to 2 times the clock rate.
4. LVCMOS and LVTTL are measured with load specified in Table 3.45.
5. These LVCMOS inputs can be placed in different VCCIO voltage. Performance may vary. Please refer to Lattice Design Software
6. These emulated outputs performance is based on externally properly terminated as described in LVDS25E (Output Only) and SubLVDSE/SubLVDSEH (Output Only).
7. All speeds are measured with fast slew.
8. For maximum differential I/O performance, only Differential I/O should be placed in the bottom I/O banks. If this is not possible, the following will impact on maximum performance:
- a. If Fast Slew Rate LVCMOS I/O are used, they should be limited to no more than nine I/O (adjacent), four I/O (same bank), 55 I/O (left/right banks) to keep degradation below 50%.
- b. If non-Differential I/O (SLOW SLEW) are placed on the bottom but not within the same bank as differential I/O, then the maximum Differential performance is degraded to 70% of original when 21 aggressors are toggling.
- c. If non-Differential I/O (SLOW SLEW) are placed within the same bank as Differential I/O then the maximum performance is degraded to 50% of original when 16 aggressor are toggling.
- d. If Differential RX/TX I/O are both placed within the same bank then the maximum performance is degraded to 90%.
- e. For DDR3/3L, LPDDR2/3 separate DQ/DQS groups from Address/Commands/CLK groups into separate banks.

4. Maximum clock frequencies are tested under best case conditions. System performance may vary upon the user environment. 5. All numbers are generated with the Lattice Radiant software.
6. This clock skew is not the internal clock network skew. Nexus devices have very low internal clock network skew that can be approximated to 0 ps. These tSKEW values measured externally at system level includes additional skew added by the I/O, wire bonding and package ball.

## **3.23. Digital Temperature Readout Characteristics**
Digital temperature Readout (DTR) is implemented in one of the channels of ADC1.
**Table 3.39. DTR Specifications[1, 2]**
|**Symbol**|**Description**|**Condition**|**Min**|**Typ**|**Max**|**Unit**|
|---|---|---|---|---|---|---|
|DTRRANGE|DTR Detect Temperature<br>Range|—|–40|—|100|°C|
|DTRACCURACY|DTR Accuracy|with external voltage*<br>reference range of 1.0 V<br>to 1.8 V|–13|±4|13|°C|
|DTRRESOLUTION|DTR Resolution|with external voltage<br>reference|–0.3|—|0.3|°C|
## **Notes:**
1. External voltage reference (VREF) should be 0.1% accurate or better. DTR sensitivity to VREF is -4.1 °C per VREF percent (for example, if the VREF is 1 % low, then the DTR reads +4.1 °C high).
2. DTR is available in Commercial/Industrial –8 and –9 speed grades.

## **Note** :
1. TERMINATE to VCCIO/2 (Single-Ended) and DIFFRENTIAL TERMINATION RESISTOR when turned on can only have one setting per bank. Only left and right banks have this feature.
2. Use of TERMINATE to VCCIO/2 and DIFFRENTIAL TERMINATION RESISTOR are mutually exclusive in an I/O bank. On-chip termination tolerance –10%/+60%.
Refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216) for on-chip termination usage and value ranges.
## **4.6. Hot Socketing Specifications**
**Table 4.6. Hot Socketing Specifications for GPIO**
|**Symbol**|**Parameter**|**Condition**|**Min**|**Typ**|**Max**|**Unit**|

## **Notes** :
- IDK is additive to IPU, IPD, or IBH.
- Hot socket specification defines when the hot socketed device's junction temperature is at 85[o] C or below. When the hot socketed device's junction temperature is above 85[o] C, the IDK current can exceed the above spec.
- Going beyond the hot socketing ranges specified here causes exponentially higher Leakage currents and potential reliability issues. A total of 64mA per 8 I/O should not be exceeded.

**Notes** :
1. Single-ended input can mix into I/O Banks with VCCIO different from the standard requires due to some of these input standards use internal supply voltage source (VCC, VCCAUX) to power the input buffer, which makes them to be independent of VCCIO voltage. For more details, please refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216). The following is a brief guideline to follow:
- a. Weak pull-up on the I/O must be set to OFF.
- b. Bank 3, Bank 4, and Bank 5 I/O can only mix into banks with VCCIO higher than the pin standard, due to clamping diode on the pin in these banks. Bank 0, Bank 1, Bank 2, Bank 6, and Bank 7 do not have this restriction.
- c. LVCMOS25 uses VCCIO supply on input buffer in Bank 0, Bank 1, Bank 2, Bank 6, and Bank 7. It can be supported with VCCIO = 3.3 V to meet the VIH and VIL requirements, but there is additional current drawn on VCCIO. Hysteresis has to be disabled when using 3.3 V supply voltage.
- d. LVCMOS15 uses VCCIO supply on input buffer in Bank 3, Bank 4, and Bank 5. It can be supported with VCCIO = 1.8 V to meet the VIH and VIL requirements, but there is additional current drawn on VCCIO.

2. Single-ended LVCMOS inputs can mixed into I/O Banks with different VCCIO, providing weak pull-up is not used. For additional information on Mixed I/O in Bank VCCIO, refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216) **.**
3. These inputs use differential input comparator in Bank 3, Bank 4, and Bank 5. The differential input comparator uses VCCAUXH power supply. These inputs require the VREF pin to provide the reference voltage in the Bank. Refer to Certus-NX High-Speed I/O Interface (FPGA-TN-02216) for details **.**
4. All differential inputs use differential input comparator in Bank 3, Bank 4, and Bank 5. The differential input comparator uses VCCAUXH power supply. There is no differential input signaling supported in Bank 0, Bank 1, Bank 2, Bank 6, and Bank 7.
5. These outputs are emulating differential output pair with single-ended output drivers with true and complement outputs driving on each of the corresponding true and complement output pair pins. The common mode voltage, VCM, is ½ * VCCIO. Refer Certus-NX High-Speed I/O Interface (FPGA-TN-02216) for details **.**
6. VCCIO = 1.35 V is only supported in Bank 3, Bank 4, and Bank 5, for use with DDR3L interface in the bank. These Input and Output standards can fit into the same bank with the VCCIO = 1.35 V.
7. LVCMOS15 input uses VCCIO supply voltage. If VCCIO is 1.8 V, the DC levels for LVCMOS15 are still met, but there could be increase in input buffer current.

**Notes** :
1. LVDS input or output are supported in Bank 3, Bank 4, and Bank 5. LVDS input uses VCCAUX on the differential input comparator, and can be located in any VCCIO voltage bank. LVDS output uses VCCIO on the differential output driver, and can only be located in bank with VCCIO = 1.8 V.
2. VICM is depending on VID, input differential voltage, so the voltage on pin cannot exceed VINP/INN(min/max) requirements. VICM(min) = VINP/INN(min) + ½ VID, VICM(max) = VINP/INN(max) – ½ VID. Values in the table is based on minimum VID of +/- 100 mV.

## **4.12.3. SubLVDS (Input Only)**
SubLVDS is a reduced-voltage form of LVDS signaling, very similar to LVDS. It is a standard used in many camera types of applications, and follow the SMIA 1.0, Part 2: CCP2 Specification. Being similar to LVDS, the Certus-NX devices can support the subLVDS input signaling with the same LVDS input buffer. The output for subLVDS is implemented in subLVDSE/subLVDSEH with a pair of LVCMOS18 output drivers (see SubLVDSE/SubLVDSEH (Output Only) section).

**Figure 4.3. SubLVDS Input Interface**
## **4.12.4. SubLVDSE/SubLVDSEH (Output Only)**
SubLVDS output uses a pair of LVCMOS18 drivers with True and Complement outputs. The VCCIO of the bank used for subLVDSE or subLVDSEH needs to be powered by 1.8V. SubLVDSE is for Bank 0, Bank 1, Bank 2, Bank 5, and Bank 6; and subLVDSEH is for Bank 3, Bank 4, and Bank 5.
Performance of the subLVDSE/subLVDSEH driver is limited to the performance of LVCMOS18.

## **4.12.5. SLVS**
Scalable Low-Voltage Signaling (SLVS) is based on a point-to-point signaling method defined in the JEDEC JESD8-13 (SLVS-400) standard. This standard evolved from the traditional LVDS standard with smaller voltage swings and a lower common-mode voltage. The 200 mV (400 mV p-p) SLVS swing contributes to a reduction in power.
The Certus-NX devices receive SLVS differential input with the LVDS input buffer. This LVDS input buffer is design to cover wide input common mode range that can meet the SLVS input standard specified by the JEDEC standard.
**Table 4.23. SLVS Input DC Characteristics**
**Parameter Description Test Conditions Min Typ Max Unit** VID Input Differential Threshold Voltage Over VICM range 70 — — mV ~~a~~ VICM Input Common Mode Voltage Half the sum of the two Inputs 70 200 330 mV
The SLVS output on Certus-NX is supported with the LVDS drivers found in Bank 3, Bank 4, and Bank 5. The LVDS driver on Certus-NX is a current controlled driver. It can be configured as LVDS driver, or configured with the 100 Ω differential termination with center-tap set to VOCM at 200 mV. This means the differential output driver can be placed into bank with VCCIO = 1.2 V, 1.5 V, or 1.8 V, even if it is powered by VCCIO.

**Notes** :
1. Maximum I/O speed is the maximum switching rate of the I/O operating within the guidelines of the defining standard. The actual interface speed performance using the I/O also depends on other factors, such as internal and external timing.
2. These numbers are characterized but not test on every device.
3. Performance is specified in MHz, as defined in clock rate when the sysI/O is used as pin. For data rate performance, this can be converted to Mbps, which equals to 2 times the clock rate.
4. LVCMOS and LVTTL are measured with load specified in Table 3.45.
5. These LVCMOS inputs can be placed in different VCCIO voltage. Performance may vary. Please refer to Lattice Design Software
6. These emulated outputs performance is based on externally properly terminated as described in LVDS25E (Output Only) and SubLVDSE/SubLVDSEH (Output Only).
7. All speeds are measured with fast slew.
8. For maximum differential I/O performance, only Differential I/O should be placed in the bottom I/O banks. If this is not possible, the following will impact on maximum performance:
- a. If Fast Slew Rate LVCMOS I/O are used, they should be limited to no more than nine I/O (adjacent), four I/O (same bank), 55 I/O (left/right banks) to keep degradation below 50%.
- b. If non-Differential I/O (SLOW SLEW) are placed on the bottom but not within the same bank as differential I/O, then the maximum Differential performance is degraded to 70% of original when 21 aggressors are toggling.
- c. If non-Differential I/O (SLOW SLEW) are placed within the same bank as Differential I/O then the maximum performance is degraded to 50% of original when 16 aggressor are toggling.
- d. No performance impact if MIPI LP and MIPI HS are in the same bank.
- e. If Differential RX/TX I/O are both placed within the same bank then the maximum performance is degraded to 90%.
- f. For DDR3/3L, LPDDR2/3 separate DQ/DQS groups from Address/Commands/CLK groups into separate banks.

**Notes** :
1. Commercial timing numbers are shown. Industrial numbers are typically slower and can be extracted from the Lattice Radiant software.
2. General I/O timing numbers are based on LVCMOS 1.8, 8 mA, Fast Slew Rate, 0 pf load. Generic DDR timing are numbers based on LVDS I/O.
- DDR3 timing numbers are based on SSTL15. LPDDR2 and LPDDR3 timing numbers are based on HSUL12.
3. Uses LVDS I/O standard for measurements.
4. Maximum clock frequencies are tested under best case conditions. System performance may vary upon the user environment.
5. All numbers are generated with the Lattice Radiant software.
6. This clock skew is not the internal clock network skew. Nexus devices have very low internal clock network skew that can be approximated to 0 ps. These tSKEW values measured externally at system level includes additional skew added by the I/O, wire bonding and package ball.
