Power Management** ## **5.1 Device States** The ATWINC3400-MR210CA module has multiple device states, based on the state of the IEEE 802.11 and Bluetooth subsystems. It is possible for both subsystems to be active at the same time. To simplify the device power consumption breakdown, the following basic states are defined. One subsystem can be active at a time: - WiFi_ON_Transmit – Device actively transmits IEEE 802.11 signal - WiFi_ON_Receive – Device actively receives IEEE 802.11 signal - BT_ON_Transmit – Device actively transmits Bluetooth signal - BT_ON_Receive – Device actively receives Bluetooth signal - Doze – Device is powered on but it does not actively transmit or receive data - Power_Down – Device core supply is powered off ## **5.2 Controlling Device States** The following table shows different device states and its power consumption. The device states can be switched using the following: - CHIP_EN – Module pin (pin 19) enables or disables the DC/DC converter - VDDIO – I/O supply voltage from external supply In the ON states, VDDIO is ON and CHIP_EN is high (at VDDIO voltage level). To change from the ON states to Power_Down state, connect the RESETN and CHIP_EN pin to logic low (GND) by following the power-down sequence mentioned in Figure 5-1. When VDDIO is OFF and CHIP_EN is low, the chip is powered off with no leakage. **Table 5-1. ATWINC3400-MR210CA Device States Current Consumption** |**Device State**|**Code Rate**|**Output Power**

Current consumption mentioned for these states is the sum of current consumed in VDDIO and VBAT voltage rails. When power is not supplied to the device (DC/DC converter output and VDDIO are OFF, at ground potential), voltage cannot be applied to the ATWINC3400-MR210CA module pins because each pin contains an ESD diode from the pin to supply. This diode turns on when voltage higher than one diodedrop is supplied to the pin. If voltage must be applied to the signal pads when 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 voltage that is more than one diode-drop below the ground to any pin. ## **5.3 Power-Up/Down Sequence** The following figure illustrates the power-up/down sequence for the ATWINC3400-MR210CA module. **Figure 5-1.

Clocking** ## **6.1 Low-Power Clock** The ATWINC3400-MR210CA module requires an external 32.768 kHz clock to be supplied at the module pin 20. This clock is used during the sleep operation. The frequency accuracy of this external clock must be within ±200 ppm. **Datasheet Preliminary** DS70005350A-page 24 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA CPU and Memory Subsystem** ## **7. CPU and Memory Subsystem** ## **7.1 Processor** The ATWINC3400-MR210CA module has two Cortus APS3 32-bit processors, one is used for Wi-Fi and the other is used for Bluetooth. In IEEE 802.11 mode, the processor performs many of the MAC functions, including but not limited to: association, authentication, power management, security key management, and MSDU aggregation/de-aggregation. In addition, the processor provides flexibility for various modes of operation, such as Station (STA) and Access Point (AP) modes. In Bluetooth mode, the processor handles multiple tasks of the Bluetooth protocol stack. ## **7.2 Memory Subsystem** The APS3 core uses a 256 KB instruction/boot ROM (160 KB for IEEE 802.11 and 96 KB for Bluetooth) along with a 420 KB instruction RAM (128 KB for IEEE 802.11 and 292 KB for Bluetooth), and a 128 KB data RAM (64 KB for IEEE 802.11 and 64 KB for Bluetooth). In addition, the device uses a 160 KB shared/exchange RAM (128 KB for IEEE 802.11 and 32 KB for Bluetooth), accessible by the processor and MAC, which allows the processor to perform various data management tasks on the Tx and Rx data packets. ## **7.3 Nonvolatile Memory** The ATWINC3400-MR210CA module has 768 bits of nonvolatile eFuse memory that can be read by the CPU after device reset. This nonvolatile One-Time-Programmable (OTP) memory can be used to store customer-specific parameters, such as the 802.11 MAC address and Bluetooth address; and various calibration information such as Tx power, crystal frequency offset, and other software-specific configuration parameters. The eFuse is partitioned into six 128-bit banks. The bit map of the first and last banks is shown in the following figure. The purpose of the first 80 bits in bank 0 and the first 56 bits in bank 5 is fixed, and the remaining bits are general-purpose software dependent bits, reserved for future use. Currently, the Bluetooth address is derived from the Wi-Fi MAC address (BT_ADDR=MAC_ADDR +1). This eliminates the need to program the first 56 bits in bank 5. Since each bank and each bit can be programmed independently, this allows for several updates of the device parameters following the initial programming. For example, if the MAC address has to be changed, Bank 1 has to be programmed with the new MAC address along with the values of Tx gain correction and frequency offset if they are used and programmed in the Bank 0. The contents of Bank 0 have to be invalidated in this case by programming the Invalid bit in the Bank 0. This will allow the firmware to use the MAC address from Bank 1. By default, ATWINC3400-MR210CA modules are programmed with the MAC address and the frequency offset bits of Bank 0. **Datasheet Preliminary** DS70005350A-page 25 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA CPU and Memory Subsystem** **Figure 7-1.

WLAN Subsystem** The WLAN subsystem is composed of the Media Access Controller (MAC), Physical Layer (PHY), and the radio. ## **8.1 MAC** The ATWINC3400-MR210CA module is designed to operate at low power, while providing high data throughput. The IEEE 802.11 MAC functions are implemented with a combination of dedicated datapath engines, hardwired control logic, and a low power, high-efficiency microprocessor. The combination of dedicated logic with a programmable processor provides optimal power efficiency and real time response while providing the flexibility to accommodate evolving standards and future feature enhancements. The dedicated datapath engines are used to implement datapath functions with heavy computational requirements. For example, a Frame Check Sequence (FCS) engine checks the Cyclic Redundancy Check (CRC) of the transmitting and receiving packets, and a cipher engine performs all the required encryption and decryption operations for the WEP, WPA-TKIP, and WPA2 CCMP-AES security requirements. Control functions, which have real time requirements, are implemented using hardwired control logic modules. These logic modules offer real time response while maintaining configurability through the processor. Examples of hardwired control logic modules are the channel access control module (implements EDCA/HCCA, Beacon Tx control, interframe spacing, and so on), protocol timer module (responsible for the Network Access vector, back-off timing, timing synchronization function, and slot management), MAC Protocol Data Unit (MPDU) handling module, aggregation/deaggregation module, block ACK controller (implements the protocol requirements for burst block communication), and Tx/Rx control Finite State Machine (FSM) (coordinates data movement between PHY and MAC interface, cipher engine, and the Direct Memory Access (DMA) interface to the Tx/Rx FIFOs). The following are the characteristics of MAC functions implemented solely in software on the microprocessor: - Functions with high memory requirements or complex data structures. Examples include association table management and power save queuing. - Functions with low computational load or without critical real time requirements. Examples include authentication and association. - Functions that require flexibility and upgradeability. Examples include beacon frame processing and QoS scheduling. ## **Features** The ATWINC3400-MR210CA MAC supports the following functions: - IEEE 802.11b/g/n - IEEE 802.11e WMM QoS EDCA/HCCA/PCF multiple access categories traffic scheduling - Advanced IEEE 802.11n features: - Transmission and reception of aggregated MPDUs (A-MPDU) - Transmission and reception of aggregated MSDUs (A-MSDU) - Immediate block acknowledgment - Reduced Interframe Spacing (RIFS) - IEEE 802.11i and WFA security with key management: **Datasheet Preliminary** DS70005350A-page 27 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA WLAN Subsystem** - WEP 64/128 - WPA-TKIP - 128-bit WPA2 CCMP (AES) - Advanced power management: - Standard IEEE 802.11 power save mode - RTS-CTS and CTS-self support - Either STA or AP mode in the infrastructure basic service set mode ## **8.2 PHY** The ATWINC3400-MR210CA module WLAN PHY is designed to achieve reliable and power-efficient physical layer communication specified by IEEE 802.11 b/g/n in single stream mode with 20 MHz bandwidth. The advanced algorithms are used to achieve maximum throughput in a real world communication environment with impairments and interference. The PHY implements all the required functions such as Fast Fourier Transform (FFT), filtering, Forward Error Correction (FEC) that is a Viterbi decoder, frequency, timing acquisition and tracking, channel estimation and equalization, carrier sensing, clear channel assessment and automatic gain control. ## **Features** The IEEE 802.11 PHY supports the following functions: - Single antenna 1x1 stream in 20 MHz channels - Supports IEEE 802.11b DSSS-CCK modulation: 1, 2, 5.5, and 11 Mbps - Supports IEEE 802.11g OFDM modulation: 6, 9, 12,18, 24, 36, 48, and 54 Mbps - Supports IEEE 802.11n HT modulations MCS0-7, 20 MHz, 800 and 400ns guard interval: 6.5, 7.2, 13.0, 14.4, 19.5, 21.7, 26.0, 28.9, 39.0, 43.3, 52.0, 57.8, 58.5, 65.0, and 72.2 Mbps - IEEE 802.11n mixed mode operation - Per packet Tx power control - Advanced channel estimation/equalization, automatic gain control, CCA, carrier/symbol recovery and frame detection ## **8.3 Radio** This section presents information describing the properties and characteristics of the ATWINC3400MR210CA and Wi-Fi radio transmit and receive performance capabilities of the device. The performance measurements are taken at the RF pin assuming 50Ω impedance; the RF performance is guaranteed for room temperature of 25[o] C with a derating of 2-3 dB at boundary conditions.

Bluetooth Low Energy 4.0** The Bluetooth subsystem implements all the mission critical real-time functions. It encodes/decodes HCI packets, constructs baseband data packages; and manages and monitors the connection status, slot usage, data flow, routing, segmentation, and buffer control. The Bluetooth subsystem supports Bluetooth Low Energy modes of operation. Supports the following advanced low energy applications: - Smart energy - Consumer wellness - Home automation - Security - Proximity detection - Entertainment - Sports and Fitness - Automotive ## **Coexistence Mechanism** The ATWINC3400 supports simultaneous usage of both Bluetooth Low Energy and Wi-Fi via a coexistence mechanism that allows the protocols to share the same radio. The radio defaults to Wi-Fi usage until a Bluetooth Low Energy event occurs (such as connection or advertising), in which case the radio is gracefully switched over for Bluetooth Low Energy use. For the duration of the Bluetooth Low Energy event, the radio is switched back and forth between Wi-Fi and Bluetooth Low Energy as demanded by the Bluetooth Low Energy activity, before returning to Wi-Fi until the next Bluetooth Low Energy event. **Datasheet Preliminary** DS70005350A-page 30 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA External Interfaces** ## **10.

The SPI interface can be used for control and for serial I/O of 802.11 data. The SPI pins are mapped as shown in the following table. The SPI is a full-duplex slave-synchronous serial interface that is available immediately following reset when pin 10 (SPI_CFG) is tied to VDDIO. **Table 10-2. SPI Interface Pin Mapping** |**Pin #**|**SPI function**| |---|---| |10|CFG: Must be tied to VDDIO| |16|SSN: Active-Low Slave Select| |15|MOSI(RXD): Serial Data Receive| |18|SCK: Serial Clock| |17|MISO(TXD): Serial Data Transmit| When the SPI is not selected, that is, when SSN is high, the SPI interface will not interfere with data transfers between the serial-master 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 MISO line. The SPI 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. The SPI SSN, MOSI, MISO, and SCK pins of the ATWINC3400-MR210CA have internal programmable pull-up resistors. These resistors should be programmed to be disabled; otherwise, if any of the SPI pins are driven to a low level while the ATWINC3400-MR210CA is in the low power sleep state, the current will flow from the VDDIO supply through the pull-up resistors, increasing the current consumption of the module. ## **10.2.2 SPI Timing** The SPI Slave interface supports four standard modes as determined by the Clock Polarity (CPOL) and Clock Phase (CPHA) settings. These modes are illustrated in the following table and figure. **Table 10-3. SPI Slave Modes** |**Mode**|**CPOL**|**CPHA**| |---|---|---| |0|0|0| |1|0|1| |2|1|0| |3|1|1| The red lines in the following figure correspond to Clock Phase = 0 and the blue lines correspond to Clock Phase = 1. **Datasheet Preliminary** DS70005350A-page 32 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA External Interfaces** **Figure 10-2.

Timing based on 15pF output loading ## **10.3 UART Interface** The ATWINC3400-MR210CA supports the Universal Asynchronous Receiver/Transmitter (UART) interface. This interface should be used for debug purposes only. The two UART pins TXD/RXD are available on pin J16 and pin J17 respectively. The UART is compatible with the RS-232 standard. The default configuration for accessing the UART interface of ATWINC3400-MR210CA is mentioned below: - Baud rate: 460800 - Data: 8 bit - Parity: None - Stop bit: 1 bit - Flow control: None 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 the UART receiving or transmitting a single packet is shown in the following figure. This example shows 7-bit data (0x45), odd parity, and two stop bits. **Important:** UART2 supports RTS and CTS flow control.

## **Note:** 1. Dimensions are in mm. 2. It is recommended to have a 5x5 grid of GND vias solidly connecting the exposed GND paddle of the module to the ground plane on the inner/other layers of the host board. This will provide a good ground and thermal transfer for the ATWINC3400-MR210CA module. **Datasheet Preliminary** DS70005350A-page 38 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA Design Consideration** ## **13. Design Consideration** This section provides the guidelines on module placement and routing to achieve the best performance. ## **13.1 Module Placement and Routing Guidelines** It is critical to follow the recommendations listed below to achieve the best RF performance: - The module must be placed on the host board and the chip antenna area must not overlap with the host board. The following figure on placement reference shows the best, poor, and worst case module placements in the host board. ## **Figure 13-1. ATWINC3400-MR210CA Placement Example** **CAUTION Caution:** Do not place the module in the middle of the host board or far away from the host board edge. - Follow the host board mechanical recommendation, ground plane and keep out recommendations as shown in the following figure. Module chip antenna is specifically tuned for this host board mechanical recommendation as shown in the following figure. The host PCB should have a thickness of 1.5 mm - Follow the module placement and keep out recommendation as shown in the following figure. - Avoid routing any traces on the top layer of the host board which will be directly below the module area. - In the keep out region, there should be no copper traces in all signal layers. - Avoid placing any components (like mechanical spacers, bumpon and so on) on the host board closer to the chip antenna region. **Datasheet Preliminary** DS70005350A-page 39 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA Design Consideration** - Place the GND polygon pour below the module on the top layer of the host board. Avoid breaks in this GND plane and ensure continuous GND plane for better RF performance. - GND polygon pour in the top layer of the host board should have a minimum area of 20 x 40 mm. - Place sufficient GND vias on host board edge and below the module for better RF performance. - It is recommended to have a 5x5 grid of GND vias solidly connecting the exposed GND paddle of the module to the ground plane of the host board. This will act as a good ground and thermal conduction path for the ATWINC3400-MR210CA module. The GND vias should have a minimum via hole size of 0.2 mm. - Antenna on the module should not be placed in direct contact or close proximity to plastic casing/objects. Keep a minimum clearance of >7 mm in all directions around the chip antenna. **Figure 13-2. ATWINC3400-MR210CA Placement Reference** ## **13.2 Antenna Performance** The ATWINC3400-MR210CA uses a chip antenna which is fed via matching network. The table below lists the technical specification of the chip antenna. **Table 13-1.

Reflow Profile Information** This section provides the guidelines for the reflow process to get the module soldered to the customer's design. ## **14.1 Storage Condition** ## **14.1.1 Moisture Barrier Bag Before Opening** A moisture barrier bag must be stored at a temperature of less than 30°C with humidity under 85% RH. The calculated shelf life for the dry-packed product is 12 months from the date the bag is sealed. ## **14.1.2 Moisture Barrier Bag Open** Humidity indicator cards must be blue, < 30%. ## **14.2 Solder Paste** The SnAgCu eutectic solder with melting temperature of 217°C is most commonly used for lead-free solder reflow application. This alloy is widely accepted in the semiconductor industry due to its low cost, relatively low melting temperature, and good thermal fatigue resistance. 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 or SENJU N705-GRN3360-K2-V Type 3, no clean paste. ## **14.3 Stencil Design** The recommended stencil is laser-cut, stainless-steel type with thickness of 100 µm to 130 µm and approximately a 1:1 ratio of stencil opening to pad dimension. To improve paste release, a positive taper with bottom opening 25 µm larger than the top is utilized. Local manufacturing experience may find other combinations of stencil thickness and aperture size to get good results. ## **14.4 Baking Conditions** This module is rated at MSL level 3. After the sealed bag is opened, no baking is required within 168 hours as long as the devices are held at ≤ 30°C/60% RH or stored at < 10% RH. The module requires baking before mounting if: - The sealed bag has been open for more than 168 hours - The humidity indicator card reads more than 10% - SIPs need to be baked for eight hours at 125°C ## **14.5 Soldering and Reflow Condition** Optimization of the reflow process is the most critical factor considered for lead-free soldering. The development of an optimal profile must account the paste characteristics, the size of the board, the density of the components, the mix of the larger and smaller components, and the peak temperature requirements of the components. An optimized reflow process is the key to ensuring a successful leadfree assembly and achieves high yield and long-term solder joint reliability. **Datasheet Preliminary** DS70005350A-page 42 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA Reflow Profile Information** ## **Temperature Profiling** Temperature profiling must be performed for all new board designs by attaching thermocouples at the solder joints, on the top surface of the larger components, and at multiple locations of the boards. This is to ensure that all components are heated to a temperature above the minimum reflow temperatures and the smaller components do not exceed the maximum temperature limit. The SnAgCu solder alloy melts at ~217°C, so the reflow temperature peak at joint level must be 15 to 20°C higher than melting temperature. The targeted solder joint temperature for the SnAgCu solder must be ~235°C. For larger or sophisticated boards with a large mix of components, it is also important to ensure that the temperature difference across the board is less than 10 degrees to minimize board warpage. The maximum temperature at the component body must not exceed the MSL3 qualification specification. ## **14.5.1 Reflow Oven** It is strongly recommended that a reflow oven equipped with more heating zones and Nitrogen atmosphere must be used for the lead-free assembly. The Nitrogen atmosphere is 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 must also be observed in the reflow process: 1. 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 2. Allowable reflow soldering iterations: - Three times based on the following reflow soldering profile (see following figure). 3. Temperature profile: - Reflow soldering must be done according to the following temperature profile (see following figure). - Peak temperature: 250°C **Datasheet Preliminary** DS70005350A-page 43 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA Reflow Profile Information** **Figure 14-1. Solder Reflow Profile** ## **Cleaning** The exposed ground paddle helps to self-align the module, avoiding pad misalignment. The use of no clean solder pastes is recommended. As a result of the reflow process, be sure to completely dry the noclean paste fluxes. This may require longer reflow profiles and/or peak temperatures toward the high end of the process window as recommended by the solder paste vendor. It is believed that uncured flux residues can lead to corrosion and/or shorting in accelerated testing and possibly the field. ## **Rework** The rework removes the mounted SIP package and replaces it with a new unit. It is recommended that once an ATWINC3400-MR210CA module is removed and it must never be reused. During the rework process, the mounted module and PCB are heated partially, and the module is removed. It is recommended to heat-proof the proximity of the mounted parts and junctions and use the best nozzle for rework that is suited to the module size. **Datasheet Preliminary** DS70005350A-page 44 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA Module Assembly Considerations** ## **15. Module Assembly Considerations** The ATWINC3400-MR210CA module is assembled with an EMI shield to ensure compliance with EMI emission and immunity rules. The EMI shield is made of a tin-plated steel (SPTE) and is not hermetically sealed. Solutions such as IPA and similar solvents can be used to clean this module. Cleaning solutions containing acid must never be used on the module. The ATWINC3400-MR210CA module is manufactured without any conformal coating applied. It is the customer's responsibility if a conformal coating is specified and/or applied to this module. **Datasheet Preliminary** DS70005350A-page 45 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA Regulatory Approval** ## **16.

All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property. - Microchip is willing to work with the customer who is concerned about the integrity of their code. **Datasheet Preliminary** DS70005350A-page 53 © 2017 Microchip Technology Inc. **ATWINC3400-MR210CA** - Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code.
