Device States** ## **5.1 Description of Device States** The ATBTLC1000-XR1100A and the ATBTLC1000-ZR110CA have multiple device states, depending on the state of the ARM processor and BLE subsystem. **Note:** The ARM is required to be powered-on if the BLE subsystem is active. - BLE_On_Transmit – Device is actively transmitting a BLE signal (Irrespective of whether ARM processor is active or not) - BLE_On_Receive – Device is actively receiving a BLE signal (Irrespective of whether ARM processor is active or not) - Ultra_Low_Power – BLE subsystem and ARM processor is powered-down (with or without RAM retention) - Power_Down – Device core supply off ## **5.1.1 Controlling the Device States** The following pins are used to switch between the main device states: - C_EN – used to enable PMU - VDDIO – I/O supply voltage from an external power supply - AO_GPIO_0 - can be used to control the device from entering/exiting Ultra_Low_Power mode To be in the Power_Down state, the VDDIO supply must be turned on and the C_EN must be maintained at logic low (at GND level). To switch between the Power_Down state and the MCU_Only state, C_EN is to be maintained at logic high (VDDIO voltage level). Once the device is in the MCU_Only state, all other state transitions are controlled entirely by software. When VDDIO supply is turned off and C_EN is in logic low, the chip is powered-off with no leakage. When VDDIO supply is turned off, voltage cannot be applied to the ATBTLC1000-XR1100A pins as each pin contains an ESD diode from the pin to supply. This diode will turn on when a voltage higher than one diode-drop is supplied to the pin. If a voltage must be applied to the signal pads while the chip is in a low power state, the VDDIO supply must be on, so the Power_Down state must be used. Similarly, to prevent the pin-to-ground diode from turning on, do not apply a voltage that is more than one diode-drop below ground to any pin. The AO_GPIO_0 pin can be used to control the device from entering and exiting Ultra_Low_Power mode. When AO_GPIO_0 is maintained in logic high state, the device will not enter Ultra_Low_Power mode. When the AO_GPIO_0 is maintained in logic low, the device will enter Ultra_Low_Power mode provided there are no BLE events to be handled. ## **5.2 Power Sequences** The power sequences for the ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA are shown in Powerup/Power-down Sequence. The timing parameters are provided in Power-up/Power-down Sequence Timing. **Datasheet Complete** DS60001505A-page 14 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** **Figure 5-1.

Pull-up/down resistor value is 96kΩ ±10% 3. In Power-On Reset state pull-up resistor is enabled in the always-on/wakeup GPIO only 4. In Power-On Default state input drivers and pull-up/down resistors are disabled in the mixed-signal GPIOs only (mixed-signal GPIOs are defaulted to analog mode, see the note below) 5. Mixed-signal GPIOs can be programmed to be in analog or digital mode for each pin: when programmed to analog mode (default), the output driver, input driver, and pull-up/down resistors are all disabled 6. In Ultra_Low_Power state always-on/wakeup GPIO does not have retention capability and behaves same as in MCU_Only or BLE_On states, also for mixed-signal GPIOs programming analog mode overrides retention functionality for each pin **Datasheet Complete** DS60001505A-page 16 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** ## **6. ATBTLC1000-XR/ZR Host Microcontroller Interface** This section describes the interface of ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA with the host MCU. The interface to be used is UART with hardware flow control. It requires two additional GPIOs and one interrupt pin from the host MCU. See the below figure: **Figure 6-1. Host Microcontroller to ATBTLC1000-XR/ZR Interface** The host wakeup pin from ATBTLC1000 can be connected to any interrupt pin of the host MCU. The host MCU could monitor this pin level and decide to wakeup based on events from ATBTLC1000. The host wakeup pin will be held in logic high ('1') by default and at conditions where there is no pending event data in the ATBTLC1000. The host wakeup pin will be held in logic low ('0') when there is event data available from ATBTLC1000 and the pin will be held in this state until all event data is sent out from ATBTLC1000. By default in BluSDK, GPIO_MS1 is used as the host wakeup pin.

Clocking** ## **7.1 Overview** **Figure 7-1. Clock Architecture** Clock Architecture provides an overview of the clock tree and clock management blocks. The BLE Clock is used to drive the BLE subsystem. The ARM clock is used to drive the Cortex-M0 MCU and its interfaces (UART, SPI, and I2C); the recommended MCU clock speed is 26MHz. The Low Power Clock is used to drive all the low-power applications like the BLE sleep timer, always-on power sequencer, always-on timer, and others. The 26MHz integrated RC Oscillator is used for most general purpose operations on the MCU and its peripherals. In cases when the BLE subsystem is not used, the RC oscillator can be used for lower power consumption. The frequency variation of this RC oscillator is up to ±50% over process, voltage, and temperature. The frequency variation of 2MHz integrated RC Oscillator is up to ±50% over process, voltage, and temperature. The 32.768kHz RTC Crystal Oscillator (RTC XO) is used for BLE operations as it will reduce power consumption by providing the best timing for wakeup precision, allowing circuits to be in low-power sleep mode for as long as possible until they need to wake up and connect during the BLE connection event. ## **7.2 26MHz Crystal Oscillator (XO)** A 26MHz crystal oscillator is integrated into the ATBTLC1000-XR1100A and ATBTC1000-ZR110CA to provide the precision clock for the BLE operations. **Datasheet Complete** DS60001505A-page 18 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** ## **7.3 32.768kHz RTC Crystal Oscillator (RTC XO)** 32.768kHz RTC Crystal Oscillator (RTC XO). ## **7.3.1 General Information** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA have a 32.768kHz RTC oscillator that is preferably used for BLE activities involving connection events. To be compliant with the BLE specifications for connection events, the frequency accuracy of this clock has to be within ±500ppm. Because of the high accuracy of the 32.768kHz crystal oscillator clock, the power consumption can be minimized by leaving radio circuits in low-power sleep mode for as long as possible until they need to wake up for the next connection timed event. The block diagram in the below Figure(a) shows how the internal low-frequency Crystal Oscillator (XO) is connected to the external crystal. The RTC XO has a programmable internal capacitance with a maximum of 15pF on each terminal, RTC_CLK_P, and RTC_CLK_N. When bypassing the crystal oscillator with an external signal, one can program down the internal capacitance to its minimum value (~1pF) for easier driving capability. The driving signal can be applied to the RTC_CLK_P terminal as shown in the below Figure (b). The need for external bypass capacitors depends on the chosen crystal characteristics. Typically, the crystal should be chosen to have a load capacitance of 7pF to minimize the oscillator current. Refer to the datasheet of the preferred crystal and take into account the on-chip capacitance. Alternatively, if an external 32.768kHz clock is available, it can be used to drive the RTC_CLK_P pin instead of using a crystal. The XO has 6pF internal capacitance on the RTC_CLK_P pin. To bypass the crystal oscillator, an external signal capable of driving 6pF can be applied to the RTC_CLK_P terminal as shown in Figure (b). RTC_CLK_N must be left unconnected when driving an external source into RTC_CLK_P. Refer to the Table 7-1 for the specification of the external clock to be supplied at RTC_CLK_P. **Figure 7-2. Connections to RTC XO** **Datasheet Complete** DS60001505A-page 19 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** **Table 7-1. 32.768kHz External Clock Specification** |**Parameter**|**Min. **|**Typ.**|**Max**|**Unit **|**Comments**| |---|---|---|---|---|---| |Oscillation frequency||32.768||kHz|Must be able to drive 6pF load @ desired frequency| |VinH|0.7||1.2|V|High level input voltage| |VinL|0||0.2||Low level input voltage| |Stability – Temperature|-250||+250|ppm|| Additional internal trimming capacitors (C_onchip) are available. They provide the possibility to tune the frequency output of RTC XO without changing the external load capacitors. ## **Note:** Refer the BluSDK BLE API Software Development Guide for details on how to enable the 32.768kHz clock output and tune the internal trimming capacitors. **Table 7-2. 32.768kHz XTAL C_onchip Programming** |**Register: pierce_cap_ctrl[3:0]**|**C_onchip [pF]**| |---|---| |0000|0.0| |0001|1.0| |0010|2.0| |0011|3.0| |0100|4.0| |0101|5.0| |0110|6.0| |0111|7.0| |1000|8.0| |1001|9.0| |1010|10.0| |1011|11.0| |1100|12.0| |1101|13.0| |1110|14.0| |1111|15.0| ## **7.3.2 RTC XO Design and Interface Specification** The RTC consists of two main blocks: The Programmable Gm stage and tuning capacitors. The programmable Gm stage is used to guarantee startup and to sustain oscillation. Tuning capacitors are used to adjust the XO center frequency and control the XO precision for different crystal models. The output of the XO is driven to the digital domain via a digital buffer stage with a supply voltage of 1.2V. **Datasheet Complete** DS60001505A-page 20 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** **Table 7-3.

CPU and Memory Subsystem** ## **8.1 ARM Subsystem** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA have an ARM Cortex-M0 32-bit processor. It is responsible for controlling the BLE Subsystem and handling all application features. The Cortex-M0 Microcontroller consists of a full 32-bit processor capable of addressing 4GB of memory. It has a RISC-like load/store instruction set and internal 3-stage Pipeline Von Neumann architecture. The Cortex-M0 processor provides a single system-level interface using AMBA technology to provide high speed, low latency memory accesses. The Cortex-M0 processor implements a complete hardware debug solution, with four hardware breakpoint and two watchpoint options. This provides high system visibility of the processor, memory, and peripherals through a 2-pin Serial Wire Debug (SWD) port that is ideal for microcontrollers and other small package devices. **Figure 8-1. ARM Cortex-M0 Subsystem** ## **8.1.1 Features** The processor features and benefits are: - Tight integration with the system peripherals to reduce area and development costs **Datasheet Complete** DS60001505A-page 25 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** - Thumb instruction set combines high code density with 32-bit performance - Integrated sleep modes using a Wakeup Interrupt Controller for low power consumption - Deterministic, high-performance interrupt handling via Nested Vector Interrupt Controller for timecritical applications - Serial Wire Debug reduces the number of pins required for debugging - DMA engine for Peripheral-to-Memory, Memory-to-Memory, and Memory-to-Peripheral operation ## **8.1.2 ARM Module Descriptions** ## **8.1.2.1** ## **Timer** The 32-bit timer block allows the CPU to generate a time tick at a programmed interval. This feature can be used for a wide variety of functions such as counting, interrupt generation, and time tracking. **Note:** Usage of this peripheral is not supported by the SDK. Datasheet will be updated once support for this feature is added in SDK. ## **8.1.2.2 Dual Timer** The APB dual-input timer module is an APB slave module consisting of two programmable 32-bit downcounters that can generate interrupts when they expire. The timer can be used in a Free-running, Periodic, or One-shot mode. **Note:** Usage of this peripheral is not supported by the SDK. Datasheet will be updated once support for this feature is added in SDK. ## **8.1.2.3** ## **Watchdog Timer** The two watchdog blocks allow the CPU to be interrupted if it has not interacted with the watchdog timer before it expires. In addition, this interrupt will be an output of the core so that it can be used to reset the CPU in the event that a direct interrupt to the CPU is not useful. This will allow the CPU to get back to a known state in the event a program is no longer executing as expected. The watchdog module applies a reset to a system in the event of a software failure, providing a way to recover from software crashes. Watchdog timer is being used by the BLE stack. It cannot be used by user application. ## **8.1.2.4** ## **Wake up Timer** This timer is a 32-bit countdown timer that operates on the 32kHz sleep clock. It can be used as a general-purpose timer for the ARM or as a wakeup source for the chip. It has the ability to be a one-time programmable timer, as it will generate an interrupt/wakeup on expiration and stop operation. It also has the ability to be programmed in an auto reload fashion where it will generate an interrupt/wakeup and then proceed to start another countdown sequence. **Note:** Usage of this peripheral is not supported by the SDK. Datasheet will be updated once support for this feature is added in SDK. ## **8.1.2.5** ## **SPI Controller** See Section SPI Master/Slave Interface. **Note:** Usage of this peripheral is not supported by the SDK. Datasheet will be updated once support for this feature is added in SDK. ## **8.1.2.6** ## **I2C Controller** See Section I2C Master/Slave Interface. **Note:** Usage of this peripheral is not supported by the SDK. Datasheet will be updated once support for this feature is added in SDK. ## **8.1.2.7** ## **UART** See Section UART Interface. **Datasheet Complete** DS60001505A-page 26 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** **Note:** Accessing and controlling the registers of this peripheral is not supported by the SDK. Datasheet will be updated once support for this feature is added in SDK. ## **8.1.2.8 DMA Controller** Direct Memory Access (DMA) allows certain hardware subsystems to access main system memory independently of the Cortex-M0 Processor. The DMA features and benefits are: - Supports any address alignment - Supports any buffer size alignment - Peripheral flow control, including peripheral block transfer - The following modes are supported: - Peripheral to peripheral transfer - Memory to memory - Memory to peripheral - Peripheral to memory - Register to memory - Interrupts for both TX done and RX done in memory and peripheral mode - Scheduled transfers - Endianness byte swapping - Watchdog timer - 4-channel operation - 32-bit Data width - AHB MUX (on read and write buses) - Command lists support - Usage of tokens **Note:** Usage of this peripheral is not supported by the SDK. Datasheet will be updated once support for this feature is added in SDK. ## **8.1.2.9 Nested Vector Interrupt Controller** External interrupt signals connect to the NVIC, and the NVIC prioritizes the interrupts. Software can set the priority of each interrupt. The NVIC and the Cortex-M0 processor core are closely coupled, providing low latency interrupt processing and efficient processing of late arriving interrupts. All NVIC registers are accessible via word transfers and are little endian. Any attempt to read or write a half-word or byte individually is unpredictable. The NVIC allows the CPU to be able to individually enable, disable each interrupt source, and hold each interrupt until it has been serviced and cleared by the CPU. **Table 8-1. NVIC Register Summary** |**Name**|**Description**| |---|---| |ISER|Interrupt Set-Enable Register| |ICER|Interrupt Clear-Enable Register| |ISPR|Interrupt Set-Pending Register| |ICPR|Interrupt Clear-Pending Register| |IPR0-IPR7|Interrupt Priority Registers| **Datasheet Complete** DS60001505A-page 27 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** For a description of each register, see the Cortex-M0 documentation from ARM. ## **8.1.2.10 GPIO Controller** The AHB GPIO is a general-purpose I/O interface unit allowing the CPU to independently control all input or output signals on the ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA. These can be used for a wide variety of functions pertaining to the application. The AHB GPIO provides a 16-bit I/O interface with the following features: - Programmable interrupt generation capability - Programmable masking support - Thread-safe operation by providing separate set and clear addresses for control registers - Inputs are sampled using a double flip-flop to avoid meta-stability issues **Note:** Usage of this peripheral is not supported by the SDK. Datasheet will be updated once support for this feature is added in SDK. ## **8.2 Memory Subsystem** The Cortex-M0 core uses a 128KB instruction/boot ROM along with a 128KB shared instruction and data RAM. ## **8.2.1 Shared Instruction and Data Memory** The Instruction and Data Memory (IDRAM1 and IDRAM2) contains instructions and data used by the ARM. The size of IDRAM1 and IDRAM2 is 128KB that can be used for BLE subsystem as well as for the user application. IDRAM1 contains three 32KB and IDRAM2 contains two 16KB memories that are accessible to the ARM and used for instruction/data storage. ## **8.2.2** ## **ROM** The ROM is used to store the boot code and BLE firmware, stack, and selected user profiles. ROM contains the 128KB memory that is accessible to the ARM. ## **8.2.3** ## **BLE Retention Memory** The BLE functionality requires 8KB retention memory for retaining state, instruction, and data when the processor either goes into Sleep Mode or Power Off Mode. The RAM is separated into specific power domains to allow tradeoff in power consumption with retention memory size. ## **8.3 Non-Volatile Memory** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA have 768 bits of non-volatile eFuse memory that can be read by the CPU after device reset. This memory region is one time programmable. It is partitioned into six 128-bit banks. Each bank is divided into 4 blocks with each block containing 32 bits of memory locations. This non-volatile one-time-programmable memory is used to store customer-specific parameters as listed below - 26 MHz XO Calibration information - UART hardware flow control pin selection - BT address The bit map for the block containing the above parameters are detailed in the following figures. **Datasheet Complete** DS60001505A-page 28 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** **Figure 8-2.

I2C Interface is a two-wire serial interface consisting of a serial data line (SDA) and a serial clock line (SCL). The ATBTLC1000-XR1100A and ATBTLC1000-110CA I2C support I2C bus Version 2.1 - 2000 and can operate in the following speed modes: - Standard mode (100kb/s) - Fast mode (400kb/s) - High-speed mode (3.4Mb/s) The I2C is a synchronous serial interface. The SDA line is a bidirectional signal and changes only while the SCL line is low, except for STOP, START, and RESTART conditions. The output drivers are opendrain to perform wire-AND functions on the bus. The maximum number of devices on the bus is limited by only the maximum capacitance specification of 400pF. Data is transmitted in byte packages. For specific information, refer to the Philips Specification entitled “The I2C -Bus Specification, Ver 2.1”. ## **10.3 SPI Master/Slave Interface** ## **10.3.1** ## **Description** ATBTLC1000-XR1100A and ATBTLC1000-ZR100CA provides a Serial Peripheral Interface (SPI) that can be configured as Master or Slave. The SPI Interface pins are mapped as shown in Table SPI Interface Pin Mapping. The SPI Interface is a full-duplex slave-synchronous serial interface. When the SPI is not selected, i.e., when SSN is high, the SPI interface will not interfere with data transfers between the serialmaster and other serial-slave devices. When the serial slave is not selected, its transmitted data output is buffered, resulting in a high impedance drive onto the serial master receive line. The SPI Slave interface responds to a protocol that allows an external host to read or write any register in the chip as well as initiate DMA transfers. **Table 10-3. SPI Interface Pin Mapping** |**Pin Name**|**SPI Function**| |---|---| |SSN|Active Low Slave Select| |SCK|Serial Clock| |MOSI|Master Out Slave In (Data)| |MISO|Master In Slave Out (Data)| ## **10.3.2 SPI Interface Modes** The SPI Interface supports four standard modes as determined by the Clock Polarity (CPOL) and Clock Phase (CPHA) settings. These modes are illustrated in Table SPI Modes and Figure SPI Clock Polarity and Clock Phase Timing. The red lines in Figure SPI Clock Polarity and Clock Phase Timing correspond to Clock Phase = 0 and the blue lines correspond to Clock Phase = 1. **Datasheet Complete** DS60001505A-page 37 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** **Table 10-4.

SPI Clock Polarity and Clock Phase Timing** ## **10.4 UART Interface** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA provide Universal Asynchronous Receiver/ Transmitter (UART) interfaces for serial communication. The Bluetooth subsystem has two UART interfaces: a 2-Pin interface with TX and RX, and a 4-pin interface with TX and RX and hardware flow control (RTS and CTS). The UART interfaces are compatible with the RS-232 standard, where the ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA operate as Data Terminal Equipment (DTE). **Caution:** The RTS and CTS are used for hardware flow control; they MUST be connected to the host MCU UART and enabled for the UART interface to be functional. The pins associated with each the UART interfaces can be enabled on several alternative pins by programming their corresponding pin-MUX control registers (see Table Pin-MUX Matrix of External Interfaces and Table Software Selectable MEGAMUX Options for available options). The UART features programmable baud rate generation with fractional clock division, which allows transmission and reception at a wide variety of standard and non-standard baud rates. The Bluetooth UART input clock is selectable between 26MHz, 13MHz, 6.5MHz, and 3.25MHz. The clock divider value is programmable as 13 integer bits and three fractional bits (with 8.0 being the smallest recommended value for normal operation). This results in the maximum supported baud rate of 26MHz/8.0 = 3.25MBd. **Datasheet Complete** DS60001505A-page 38 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** The UART can be configured for seven or eight-bit operation, with or without parity, with four different parity types (odd, even, mark, or space), and with one or two stop bits. It also has RX and TX FIFOs, which ensure reliable high-speed reception and low software overhead transmission. FIFO size is 4 x 8 for both RX and TX direction. The UART also has status registers showing the number of received characters available in the FIFO and various error conditions, as well the ability to generate interrupts based on these status bits. An example of UART receiving or transmitting a single packet is shown in Figure Example of UART RX or TX Packet. This example shows 7-bit data (0x45), odd parity, and two stop bits. **Figure 10-2. Example of UART RX or TX Packet** ## **10.5 GPIOs** 15 General Purpose Input/Output (GPIO) pins total, labeled LP_GPIO, GPIO_MS, and AO_GPIO, are available to allow for application specific functions. Each GPIO pin can be programmed as an input (the value of the pin can be read by the host or internal processor) or as an output. The host or internal processor can program the output values. LP_GPIO are digital interface pins, GPIO_MS are mixed signal/analog interface pins, and AO_GPIO is an always-on digital interface pin that can detect interrupt signals while in deep sleep mode for wake-up purposes. The LP_GPIO have interrupt capability, but only when in active/standby mode. In sleep mode, they are turned off to save power consumption. ## **10.6 Analog to Digital Converter (ADC)** ## **10.6.1 Overview** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA have an integrated Successive Approximation Register (SAR) ADC with 11-bit resolution and variable conversion speed up 1MS/s. The key building blocks are the capacitive DAC, comparator, and synchronous SAR engine as shown in Figure SAR ADC Block Diagram. **Datasheet Complete** DS60001505A-page 39 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** **Figure 10-3. SAR ADC Block Diagram** The ADC reference voltage can be either generated internally or set externally via one of the four available Mixed Signal GPIO pins on the ATBTLC1000-XR1100A and the ATBTLC1000-ZR110CA. There are two modes of operation: High resolution (11-bit): Set the reference voltage to half the supply voltage or below. In this condition the input signal dynamic range is equal to twice the reference voltage (ENOB=10bit). Medium Resolution (10-bit) : Set the reference voltage to any value below supply voltage (up to supply voltage - 300mV) and in this condition the input dynamic range is from zero to the reference voltage (ENOB = 9bit). Four input channels are time multiplexed to the input of the SAR ADC. However, on the ATBTLC1000, only four channel inputs are accessible from the outside, through pins 28, 29, 31, and 32 (Mixed Signal GPIO pins). In power saving mode, the internal reference voltage is completely off and the reference voltage is set externally. The ADC characteristics are summarized in Table SAR ADC Characteristics. **Table 10-5. SAR ADC Characteristics** |Conversion rate|1ks → 1MS| |---|---| |Selectable Resolution|10 → 11bit| |Power consumption|13.5µA (at 100KS/s)(1)| ## **Note:** 1. With external reference. ## **10.6.2 Timing** The ADC timing is shown in Figure SAR ADC Timing. The input signal is sampled twice, in the first sampling cycle the input range is defined either to be above reference voltage or below it and in the second sampling instant the ADC start its normal operation. The ADC takes two sampling instants and N-1 conversion cycle (N=ADC resolution) and one cycle to sample the data out. Therefore, for the 11-bit resolution, it takes 13 clock cycles to do one Sample conversion. The Input clock equals N+2 the sampling clock frequency (N is the ADC resolution). **Datasheet Complete** DS60001505A-page 40 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** CONV signal : Gives indication about end of conversion. SAMPL : The input signal is sampled when this signal is high. RST ENG : When High SAR Engine is in reset mode (SAR engine output is set to mid-scale). ## **Figure 10-4. SAR ADC Timing** ## **10.7 Software Programmable Timer and Pulse Width Modulator** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA contain four individually configurable pulse width modulator (PWM) blocks to provide external control voltages. The base frequency of the PWM block (fPWM _base) is derived from the XO clock (26MHz) or the RC oscillator followed by a programmable divider. The frequency of each PWM pulse (fPWM ) is programmable in steps according to the following relationship: = ~~——|—fPwmM base~~ 64*2 The duty cycle of each PWM signal is configurable with 10-bit resolution (minimum duty cycle is 1/1024 and the maximum is 1023/1024). fPWM base can be selected to have different values according to Table fPWM Range for Different fPWM Base Frequencies. Minimum and maximum frequencies supported for each clock selection are listed in the table as well. **Table 10-6. fPWM Range for Different fPWM Base Frequencies** |**fPWMbase**|**fPWMmax.**|**fPWMmin.**| |---|---|---| |26MHz|406.25kHz|1.586kHz| |13MHz|203.125kHz|793.25Hz| |6.5MHz|101.562kHz|396.72Hz| |3.25MHz|50.781kHz|198.36Hz| ## **10.8 Clock Output** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA have an option to output a clock. The clock can be output to any GPIO pin via the test MUX. Note that this feature requires that the ARM and BLE power domains stay on. If BLE is not used, the clocks to the BLE core are gated off, resulting in small leakage. The following two methods can be used to output a clock. **Note:** **Datasheet Complete** DS60001505A-page 41 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** Refer the BluSDK BLE API Software Development Guide for details on how to enable the 32.768kHz clock output. ## **10.8.1 Variable Frequency Clock Output Using Fractional Divider** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA can output the variable frequency ADC clock using a fractional divider of the 26MHz oscillator. This clock needs to be enabled using bit 10 of the lpmcu_clock_enables_1 register. The clock frequency can be controlled by the divider ratio using the sens_adc_clk_ctrl register (12-bits integer part, 8-bit fractional part).The division ratio can vary from 2 to 4096 delivering output frequency between 6.35kHz to 13MHz. This is a digital divider with pulse swallowing implementation so the clock edges may not be at exact intervals for the fractional ratios. However, it is exact for integer division ratios. ## **10.8.2 Fixed Frequency Clock Output** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA can output the following fixed-frequency clocks: - 52MHz derived from XO - 26MHz derived from XO - 2MHz derived from the 2MHz RC Osc. - 31.25kHz derived from the 2MHz RC Osc. - 32.768kHz derived from the RTC XO - 26MHz derived from 26MHz RC Osc. - 6.5MHz derived from XO - 3.25MHz derived from 26MHz RC Osc. For clocks 26MHz and above, ensure that external pad load on the board is minimized to get a clean waveform. ## **10.9 Three-axis Quadrature Decoder** The ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA have a three-axis Quadrature decoder (X, Y, and Z) that can determine the direction and speed of movement on three axes, requiring in total six GPIO pins to interface with the sensors. The sensors are expected to provide pulse trains as inputs to the quadrature decoder. Each axis channel input will have two pulses with ±90 degrees phase shift depending on the direction of movement. The decoder counts the edges of the two waveforms to determine the speed and uses the phase relationship between the two inputs to determine the direction of motion. The decoder is configured to interrupt ARM based on independent thresholds for each direction. Each quadrature clock counter (X, Y, and Z) is an unsigned 16-bit counter and the system clock uses a programmable sampling clock ranging from 26MHz, 13, 6.5, to 3.25MHz. If wakeup is desired from threshold detection on an axis input, an always-on GPIO needs to be used (there are three always-on GPIOs on ATBTLC1000-XR1100A and ATBTLC1000-ZR110CA). **Datasheet Complete** DS60001505A-page 42 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** ## **11. Electrical Characteristics** There are voltage ranges where different VDDIO levels apply. The reason for this separation is for the IO drivers whose drive strength is directly proportional to the IO supply voltage. In the ATBTLC1000 products, there is a large gap in the IO supply voltage range (1.8 to 4.3v). A guarantee on drive strength across this voltage range would be intolerable to most vendors who only use a subsection of the IO supply range. As such, these voltages are segmented into three manageable sections referenced as VDDIOL, VDDIOM, and VDDIOH in tables listed in this document. ## **11.1 Absolute Maximum Ratings** **Table 11-1. Absolute Maximum Ratings** |**Symbol**|**Characteristics**|**Min.**|**Max.**|**Unit**| |---|---|---|---|---| |VDDIO|I/O Supply Voltage|-0.3|5.0|V| |VBAT|Battery Supply Voltage|-0.3|5.0|| |VIN(1)|Digital Input Voltage|-0.3|VDDIO|| |VAIN(2)|Analog Input Voltage|-0.3|1.5|| |VESDHBM (3)|ESD Human Body Model|-1000, -2000 (see notes

For VESDHBM, each pin is classified as Class 1, or Class 2, or both: - The Class 1 pins include all the pins (both analog and digital) - The Class 2 pins include all digital pins only - VESDHBM is ±1kV for Class1 pins. VESDHBM is ±2kV for Class2 pins ## **11.2 Recommended Operating Conditions** **Table 11-2.

VBAT must not be less than VDDIO. **Datasheet Complete** DS60001505A-page 43 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** 2. When powering up the device, VBAT must be greater or equal to 1.9V to ensure BOD does not trigger. BOD threshold is typically 1.8V and the device will be held in reset if VBAT is near this threshold on startup. After startup, BOD can be disabled and the device can operate down to 1.8V. ## **11.3 DC Characteristics** Table DC Electrical Characteristics provides the DC characteristics for the digital pads. **Table 11-3.

ATBTLC1000-XR1100A Design Considerations** The ATBTLC1000-XR1100A is offered in a shielded Land Grid Array (LGA) package with organic laminate substrates. The LGA package makes the second level interconnect (from package to the customer PCB) with an array of solderable surfaces. This may consist of a layout similar to a BGA with no solder spheres. However, it may also have an arbitrary arrangement of solderable surfaces that typically includes large planes for grounding or thermal dissipation, smaller lands for signals or shielding grounds, and in some cases, mechanical reinforcement features for mechanical durability. ## **14.1 Layout Recommendation** Referring to the SiP footprint dimensions in Figure ATBTLC1000-XR1100A Package Outline Drawing, it is recommended to use solder mask defined with PCB pads 0.22 mm wide that have a 0.4 mm pitch. A Sample PCB pad layout in Figure PCB Footprint For ATBTLC1000-XR1100A shows the required vias for the center ground paddle. **Figure 14-1. PCB Footprint For ATBTLC1000-XR1100A** **==> picture [223 x 32] intentionally omitted <==** **----- Start of picture text -----**
EctidiWd&
**----- End of picture text -----**
The land design on the customer PCB should follow the following rules: 1. The solderable area on the customer PCB should match the nominal solderable area on the LGA package 1:1. 2. The solderable area should be finished with organic surface protectant (OSP), NiAu, or a solder cladding. 3. The decision on whether to have a solder mask defined (SMD) land or a non-solder mask defined (NSMD) land depends on the application space. - 3.1. SMD: If field reliability is at risk due to impact failures such as dropping a hand-held portable application, then the SMD land is recommended to optimize mechanical durability. - 3.2. NSMD: If field reliability is at risk due to a solder fatigue failure (temperature cycle related open circuits), then the NSMD land is recommended to maximize solder joint life. ## **14.1.1 Power and Ground** Proper grounding is essential for correct operation of the SiP and peak performance. Figure ATBTLC1000-XR1100A Package Outline Drawing shows the bottom view of the ATBTLC1000-XR1100A SiP with exposed ground pads. The SiP exposed ground pads must be soldered to customer PCB ground plane. A solid inner layer ground plane should be provided. The center ground paddle of the SiP must **Datasheet Complete** DS60001505A-page 62 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** have a grid of ground vias solidly connecting the pad to the inner layer ground plane (one via per exposed center ground pads J41~J49). Dedicate one layer as a ground plane, preferably the second layer from the top. Make sure that this ground plane does not get broken up by routes. Power can route on all layers except the ground layer. Power supply routes should be heavy copper fill planes to ensure the lowest possible inductance. The power pins of the ATBTLC1000-XR1100A should have a via directly to the power plane as close to the pin as possible. Decoupling capacitors should have a via right next to the capacitor pin and this via should go directly down to the power plane – that is to say, the capacitor should not route to the power plane through a long trace. The ground side of the decoupling capacitor should have a via right next to the pad which goes directly down to the ground plane. Each decoupling capacitor should have its own via directly to the ground plane and directly to the power plane right next to the pad. The decoupling capacitors should be placed as close to the pin that it is filtering as possible. ## **14.1.2 Antenna** When designing in the ATBTLC1000-XR1100A, it is important to pay attention to the following recommendations for antenna placement: 1. Make sure to choose an antenna that covers the proper frequency band; 2.400GHz to 2.500GHz. 2. Assure that the antenna is designed matched to 50Ω input impedance. 3. Talk to the antenna vendor and make sure it is understood that the full frequency range must be covered by the antenna. 4. Be sure to follow the antenna vendors best practice layout recommendations when placing the antenna in the customer PCB design. 5. The customer PCB pad that the antenna is connected to must be properly designed for 50Ω impedance. 6. Make sure that the trace from the RF pin on the ATBTLC1000-XR1100A to the antenna matching circuitry has a 50Ω impedance. 7. Do not enclose the antenna within a metal shield. 8. Keep any components that may radiate noise or signals within the 2.4GHz – 2.5GHz frequency band far away from the antenna and RF traces or better yet, shield the noisy components. Any noise radiated from the customer PCB in this frequency band will degrade the sensitivity of the ATBTLC1000-XR1100A device. **Datasheet Complete** DS60001505A-page 63 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** ## **15. ATBTLC1000-ZR110CA Design Considerations** ## **15.1 Placement and Routing Guidelines** It is critical to follow the recommendations listed below to achieve the best RF performance ATBTLC1000-ZR110CA module: 1. The customer PCB design should have a solid ground plane. The center ground Paddle of the module must be soldered to the ground plane with an array of vias as shown in Figure Customer PCB Top View Footprint. The module ground pins should have ground vias either on or right next to the customer PCB pad. 2. When the ATBTLC1000-ZR110CA is placed on the customer PCB, a provision for the antenna must be made. See the references in Figure ATBTLC1000-ZR110CA Placement Examples. The antenna should not be placed directly on top of the customer PCB design as seen in Figure ATBTLC1000ZR110CA Placement Examples (a). The best placement, for example, is placing the module at the edge of the board such that the module edge with the antenna extends beyond the main board edge by 3mm as shown in the Figure ATBTLC1000-ZR110CA Placement Examples (b). Alternatively, an acceptable case could be to provide a cutout in the customer PCB as shown in Figure ATBTLC1000-ZR110CA Placement Examples (c). The cutout should be 7.5mm (minimum) x 3mm as shown in the Figure PCB Keep Out Area 3. Keep large metal objects as far away as possible from the antenna, to avoid electromagnetic field blocking 4. Do not enclose the antenna within a metal shield 5. Keep any components that may radiate noise or signals within the 2.4GHz – 2.5GHz frequency band far away from the antenna or better yet, shield those components. Any noise radiated from the customer PCB in this frequency band will degrade the sensitivity of the ATBTLC1000-ZR110CA. ## **Figure 15-1. ATBTLC1000-ZR110CA Placement Examples** **Datasheet Complete** DS60001505A-page 64 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** **Figure 15-2. PCB Keep Out Area** ## **15.2 Interferers** One of the biggest problems with RF devices is poor performance due to interferers on the board radiating noise into the antenna or coupling into the RF traces going to input LNA. Care must be taken to make sure that there is no noisy circuitry placed anywhere near the antenna or the RF traces. All noise generating circuits should also be shielded so they do not radiate noise that is picked up by the antenna. This applies to all layers. Even if there is a ground plane on a layer between the RF route and another signal, the ground return current will flow on the ground plane and couple into the RF traces. **Datasheet Complete** DS60001505A-page 65 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** ## **16. Reflow Profile Information** This section provides guidelines for the reflow process in soldering the ATBTLC1000-XR1100A or the ATBTLC1000-ZR110CA to the customer’s design. ## **16.1 Storage Condition** ## **16.1.1 Moisture Barrier Bag Before Opened** A moisture barrier bag must be stored in a temperature of less than 30°C with humidity under 85% RH. The calculated shelf life for the dry-packed product shall be 12 months from the date the bag is sealed. ## **16.1.2 Moisture Barrier Bag Open** Humidity indicator cards must be blue, < 30%. ## **16.2 Stencil Design** The recommended stencil is laser-cut, stainless-steel type with a thickness of 75µm to 100µm and approximately a 1:1 ratio of stencil opening to pad dimension. To improve paste release, a positive taper with bottom opening 25µm larger than the top can be utilized. Local manufacturing experience may find other combinations of stencil thickness and aperture size to get good results. ## **16.3 Soldering and Reflow Conditions** ## **16.3.1 Reflow Oven** It is strongly recommended that a reflow oven equipped with more heating zones and Nitrogen atmosphere be used for lead-free assembly. Nitrogen atmosphere has shown to improve the wet-ability and reduce temperature gradient across the board. It can also enhance the appearance of the solder joints by reducing the effects of oxidation. The following items should also be observed in the reflow process: Some recommended pastes include - NC-SMQ[®] 230 flux and Indalloy[®] 241 solder paste made up of 95.5 Sn/3.8 Ag/0.7 Cu - SENJU N705-GRN3360-K2-V Type 3, no clean paste. Allowable reflow soldering iterations: - Three times based on the following reflow soldering profile (see Figure Solder Reflow Profile). Temperature profile: - Reflow soldering shall be done according to the following temperature profile (see Figure Solder Reflow Profile). - Peak temperature: 250°C. ## **16.4 Baking Conditions** This module is rated at MSL level 3. After sealed bag is opened, no baking is required within 168 hours so long as the devices are held at <= 30 oC/60% RH or stored at <10% RH. The module will require baking before mounting if: **Datasheet Complete** DS60001505A-page 66 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** - The sealed bag has been open for > 168 hours. - Humidity Indicator Card reads >10%. - SiP’s need to be baked for 8 hours at 125 oC. **Figure 16-1. Solder Reflow Profile** ## **16.5 Module Assembly Considerations** The Microchip ATBTLC1000-ZR110CA module is manufactured without any conformal coating applied. It is the customer’s responsibility if a conformal coating is specified and or applied to the ATBTLC1000ZR110CA module. Solutions like IPA and similar solvents can be used to clean the ATBTLC1000-ZR110CA module. However, cleaning solutions, which contain acid, should never be used on the module. **Datasheet Complete** DS60001505A-page 67 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** ## **17.

The host device must be labeled to display the Industry Canada certification number of the module, preceded by the words “Contains transmitter module”, or the word “Contains”, or similar wording expressing the same meaning, as follows: ## **ATBTLC1000-ZR110CA:** ## **Contains Transmitter Module** **IC:** 20266-BTLC1000ZR User Manual Notice for License-Exempt Radio Apparatus (from Section 8.4 RSS-Gen, Issue 4, November 2014): User manuals for license-exempt radio apparatus shall contain the following or equivalent notice in a conspicuous location in the user manual or alternatively on the device or both: **Datasheet Complete** DS60001505A-page 69 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** This device complies with Industry Canada license exempt RSS standard(s). Operation is subject to the following two conditions: 1. This device may not cause interference, and 2. This device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes: 1. l'appareil ne doit pas produire de brouillage, et 2. l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Transmitter Antenna (From Section 8.3 RSS-GEN, Issue 4, November 2014): User manuals, for transmitters shall display the following notice in a conspicuous location: Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établisse-ment d'une communication satisfaisante. The above notice may be affixed to the device instead of displayed in the user manual. ## **17.2.2 RF Exposure** All transmitters regulated by IC must comply with RF exposure requirements listed in RSS-102 - Radio Frequency (RF) Exposure Compliance of Radio communication Apparatus (All Frequency Bands). This transmitter is restricted for use with a specific antenna tested in this application for certification, and must not be co-located or operating in conjunction with any other antenna or transmitters within a host device, except in accordance with Canada multi-transmitter product procedures. ## **17.2.3 Helpful Websites** Industry Canada: http://www.ic.gc.ca/ ## **17.3 Europe** The ATBTLC1000-ZR110CA module is in progress to be an Radio Equipment Directive (RED) assessed radio module that is CE marked and has been manufactured and tested with the intention of being integrated into a final product. The ATBTLC1000-ZR110CA module has been tested to RED 2014/53/EU Essential Requirements for Health and Safety (Article (3.1(a)), Electromagnetic Compatibility (EMC) (Article 3.1(b)), and Radio (Article 3.2) and are summarized in Table Table 17-1. A Notified Body Type Examination Certificate is pending. **Datasheet Complete** DS60001505A-page 70 © 2017 Microchip Technology Inc. **ATBTLC1000XR/ZR** The ETSI provides guidance on modular devices in “Guide to the application of harmonised standards covering articles 3.1b and 3.2 of the Directive 2014/53/EU (RED) to multi-radio and combined radio and non-radio equipment” document available for download from the following location: http://www.etsi.org/ deliver/etsi_eg/203300_203399/203367/01.01.01_60/eg_203367v010101p.pdf ## **Note:** To maintain conformance to the testing listed in Table Table 17-1 , the module shall be installed in accordance withe installation instructions in this data sheet and shall not be modified When integrating a radio module into a completed product the integrator becomes the manufacturer of the final product and is therefore responsible for demonstrating compliance of the final product with the essential requirements against the RED ## **17.3.1 Labeling and User Information Requirements** The label on the final product which contains the ATBTLC1000-ZR110CA module must follow CE marking requirements. ## **17.3.2 Conformity Assessment** From ETSI Guidance Note EG 203367, section 6.1 Non-radio products are combined with a radio product: If the manufacturer of the combined equipment installs the radio product in a host non-radio product in equivalent assessment conditions (i.e. host equivalent to the one used for the assessment of the radio product) and according to the installation instructions for the radio product, then no additional assessment of the combined equipment against article 3.2 of the RED is required. The European Compliance Testing listed in Table Table 17-1 was performed using the integral ceramic chip antenna. **Table 17-1.
