The block diagram in Figure 5-1(a) shows how the internal Crystal Oscillator (XO) is connected to the external crystal. The XO has 5pF internal capacitance on each terminal XO_P and XO_N. To bypass the crystal oscillator with an external reference, an external signal capable of driving 5pF can be applied to the XO_N terminal as shown Figure 5-1(b).

Alternatively, ATWILC1000A allows for an external 32kHz clock to be used for this purpose, which is provided through Pin 24 (RTC_CLK). Software selects whether the internal clock or external clock is used. The internal low-power clock is ring-oscillator based and has accuracy within 10,000ppm. When using the internal low-power clock, the advance wakeup time in beacon monitoring mode has to be increased by about 1% of the sleep time to compensate for the oscillator inaccuracy. For example, for the DTIM interval value of 1, wakeup time has to be increased by 1ms. For any application targeting very low power consumption, an external 32kHz RTC clock should be used. 6 CPU and Memory Subsystems 6.1 Processor ATWILC1000A has a Cortus APS3 32-bit processor. This 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 STA and AP modes. 10 ATWILC1000A-MUT [DATASHEET] 1 Atmel-42351C-ATWILC1000A-MUT-SmartConnect-Datasheet_022015 0 6.2 Memory Subsystem The APS3 core uses a 128KB instruction/boot ROM along with a 128KB instruction RAM and a 64KB data RAM. In addition, the device uses a 128KB shared RAM, accessible by the processor and MAC, which allows the APS3 core to perform various data management tasks on the TX and RX data packets. 6.3 Non-Volatile Memory (EFuse) ATWILC1000A has 768 bits of non-volatile EFuse memory that can be read by the CPU after device reset. This non-volatile one-time-programmable (OTP) memory can be used to store customer-specific parameters, such as MAC address; various calibration information, such as TX power, crystal frequency offset, etc; and other software-specific configuration parameters. The EFuse is partitioned into six 128-bit banks. Each bank has the same bit map, which is shown in Figure 6-1. The purpose of the first 80 bits in each bank is fixed, and the remaining 48 bits are general-purpose software dependent bits, or reserved for future use. Since each bank can be programmed independently, this allows for several updates of the device parameters following the initial programming, e.g. updating MAC address. Refer to ATWILC1000A Programming Guide for the EFuse programming instructions. Flags 8 Bank 0 F 48 MAC ADDR 7 8 G Used 1 15 Freq.

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. Dedicated datapath engines are used to implement data path functions with heavy computational. For example, an FCS engine checks the CRC of the transmitting and receiving packets, and a cipher engine performs all the required encryption and decryption operations for the WEP, WPA-TKIP, WPA2 CCMP-AES, and WAPI 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 via the processor. Examples of hardwired control logic modules are the channel access control module (implements EDCA/HCCA, Beacon TX control, interframe spacing, etc.), protocol timer module (responsible for the Network Access Vector, back-off timing, timing synchronization function, and slot management), MPDU handling module, aggregation/deaggregation module, block ACK controller (implements the protocol requirements for burst block communication), and TX/RX control FSMs (coordinate data movement between PHY-MAC interface, cipher engine, and the DMA interface to the TX/RX FIFOs). The MAC functions implemented solely in software on the microprocessor have the following characteristics: 12 Functions with high memory requirements or complex data structures. Examples are association table management and power save queuing. Functions with low computational load or without critical real-time requirements. Examples are authentication and association. ATWILC1000A-MUT [DATASHEET] 1 Atmel-42351C-ATWILC1000A-MUT-SmartConnect-Datasheet_022015 2 Functions which need flexibility and upgradeability. Examples are beacon frame processing and QoS scheduling. 7.2 PHY 7.2.1 Features The ATWILC1000A IEEE802.11 PHY supports the following functions: 7.2.2 Single antenna 1x1 stream in 20MHz channels Supports IEEE 802.11b DSSS-CCK modulation: 1, 2, 5.5, 11Mbps Supports IEEE 802.11g OFDM modulation: 6, 9, 12,18, 24, 36, 48, 54Mbps Supports IEEE 802.11n HT modulations MCS0-7, 20MHz, 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, 72.2Mbps 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 Description The ATWILC1000A 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 20MHz bandwidth. Advanced algorithms have been employed to achieve maximum throughput in a real world communication environment with impairments and interference. The PHY implements all the required functions such as FFT, filtering, FEC (Viterbi decoder), frequency and timing acquisition and tracking, channel estimation and equalization, carrier sensing and clear channel assessment, as well as the automatic gain control. 7.3 Radio 7.3.1 Receiver Performance Radio Performance under Typical Conditions: VBAT=3.6V; VDDIO=3.3V; Temp: 25C.

External Interfaces ATWILC1000A external interfaces include I2C Slave for control, SPI Slave and SDIO Slave for control and data transfer, SPI Master for external Flash, I2C Master for external EEPROM, UART for debug, control, and data transfer, General Purpose Input/Output (GPIO) pins, and a Wi-Fi/Bluetooth coexistence interface. With the exception of the SPI Slave and SDIO Slave host interfaces, which are selected using the dedicated SDIO_SPI_CFG pin, the other interfaces can be assigned to various pins by programming the corresponding pin muxing control register for each pin to a specific value between 0 and 6.The default values of these registers are 0, which is GPIO mode. The summary of the available interfaces and their corresponding pin mux settings is shown in Table 8-1. For specific programming instructions refer to ATWILC1000A Programming Guide. ATWILC1000A-MUT [DATASHEET] Atmel-42351C-ATWILC1000A-MUT-SmartConnect-Datasheet_022015 15 1 5 Table 8-1. 8.1 Pin-Mux Matrix of External Interfaces I2C Slave Interface The I2C Slave interface, used primarily for control by the host processor, is a two-wire serial interface consisting of a serial data line (SDA, Pin 33) and a serial clock (SCL, Pin 32). It responds to the seven bit address value 0x60. The ATWILC1000A I2C supports I2C bus Version 2.1 - 2000 and can operate in standard mode (with data rates up to 100Kb/s) and fast mode (with data rates up to 400Kb/s). The I2C Slave 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 open-drain 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, Version 2.1". The I2C Slave timing is provided in Figure 8-1 and Table 8-2. Figure 8-1.

The I2C Master is a two-wire serial interface consisting of a serial data line (SDA) and a serial clock line (SCL). SDA can be configured on one of the following pins: GPIO1 (pin 24), GPIO6 (pin 31), or I2C_SDA (pin 33). SCL can be configured on one of the following pins: GPIO0 (pin 10), GPIO4 (pin 29), or I2C_SCL (pin 32). For more specific instructions refer to ATWILC1000A Programming Guide. The I2C Master interface supports three speeds: Standard mode (100kb/s) Fast mode (400kb/s) High-speed mode (3.4Mb/s) The timing diagram of the I2C Master interface is the same as that of the I2C Slave interface (see Figure 8-1). The timing parameters of I2C Master are shown in Table 8-3. Table 8-3.

The SPI Slave interface can be used for control and for serial I/O of 802.11 data. The SPI Slave pins are mapped as shown in Table 8-4. The RXD pin is same as Master Output, Slave Input (MOSI), and the TXD pin is same as Master Input, Slave Output (MISO). The SPI Slave is a full-duplex slave-synchronous serial interface that is available immediately following reset when pin 9 (SDIO_SPI_CFG) is tied to VDDIO. Table 8-4. SPI Slave Interface Pin Mapping Pin # SPI Function 9 CFG: Must be tied to VDDIO 16 SSN: Active Low Slave Select 18 SCK: Serial Clock 13 RXD: Serial Data Receive (MOSI) 17 TXD: Serial Data Transmit (MISO) When the SPI is not selected, i.e., 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 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. For the details of the SPI protocol and more specific instructions refer to ATWILC1000A Programming Guide. 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 0 and Figure 8-2. The red lines in Figure 8-2 correspond to Clock Phase = 0 and the blue lines correspond to Clock Phase = 1. 18 ATWILC1000A-MUT [DATASHEET] 1 Atmel-42351C-ATWILC1000A-MUT-SmartConnect-Datasheet_022015 8 Table 8-5.

The SPI Master interface supports all four standard modes of clock polarity and clock phase shown in 0. External SPI flash memory is accessed by a processor programming commands to the SPI Master interface, which in turn initiates a SPI master access to the flash.

The interface supports the 1-bit/4-bit SD transfer mode at the clock range of 0-50MHz. The Host can use this interface to read and write from any register within the chip as well as configure the ATWILC1000A for data DMA. To use this interface, pin 9 (SDIO_SPI_CFG) must be grounded. The SDIO Slave pins are mapped as shown in Table 8-9. Table 8-9.

During the normal initialization and interrogation of the card by the host, the card will identify itself as an SDIO device. The host software will obtain the card information in a tuple (linked list) format and determine if that card's I/O function(s) are acceptable to activate. If the card is acceptable, it will be allowed to power up fully and start the I/O function(s) built into it. The SD memory card communication is based on an advanced 9-pin interface (Clock, Command, 4 Data and 3 Power lines) designed to operate at maximum operating frequency of 50MHz. The SDIO Slave interface has the following features: Meets SDIO card specification version 2.0 Host clock rate variable between 0 and 50MHz 1 bit/4-bit SD bus modes supported Allows card to interrupt host Responds to Direct read/write (IO52) and Extended read/write (IO53) transactions.

It is intended primarily for debugging, and it can also be used for control or data transfer if the baud rate is sufficient for a given application. The UART is compatible with the RS-232 standard, where ATWILC1000A operates as Data Terminal Equipment (DTE). It has a two-pin RXD/TXD interface, where RXD can be enabled on one of four alternative pins and TXD can be enabled on one of three alternative pins by programming their corresponding pin mux control registers to 3 (see Table 8-1). 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 UART input clock is selectable between 10MHz, 5MHz, 2.5MHz, and 1.25MHz. The clock divider value is programmable as 13 integer bits and 3 fractional bits (with 8.0 being the smallest recommended value for normal operation). This results in the maximum supported baud rate of 10MHz/8.0 = 1.25MBd. 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 8-6. This example shows 7-bit data (0x45), odd parity, and two stop bits. For more specific instructions refer to ATWILC1000A Programming Guide. Figure 8-6. 8.7 Example of UART Rx or Tx Packet Wi-Fi/Bluetooth Coexistence ATWILC1000A supports 2-wire and 3-wire Wi-Fi/Bluetooth Coexistence signaling conforming to the IEEE 802.15.2-2003 standard, Part 15.2. The type of coexistence interface used (2 or 3 wire) is chosen to be compatible with the specific Bluetooth device used in a given application. Table 8-11 shows a usage example of the 2-wire interface using the GPIO3 and GPIO4 pins; 3-wire interface using the GPIO3, GPIO4, and GPIO5 pins; For more specific instructions on configuring Coexistence refer to ATWILC1000A Programming Guide.

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 output values can be programmed by the host or internal processor), where the default mode after power-up is input. GPIOs 7 and 8 are only available when the host does not use the SDIO interface, which shares two of its pins with these GPIOs. Therefore, for SDIO-based applications, seven GPIOs (0-6) are available. For more specific usage instructions refer to ATWILC1000A Programming Guide. 9 Power Management 9.1 Power Architecture ATWILC1000A uses an innovative power architecture to eliminate the need for external regulators and reduce the number of off-chip components. This architecture is shown in Figure 9-1. The Power Management Unit (PMU) has a DC/DC Converter that converts VBATT to the core supply used by the digital and RF/AMS blocks. Table 9-1 shows the typical values for the digital and RF/AMS core voltages. The PA and EFuse are supplied by dedicated LDOs, and the VCO is supplied by a separate LDO structure. 24 ATWILC1000A-MUT [DATASHEET] 2 Atmel-42351C-ATWILC1000A-MUT-SmartConnect-Datasheet_022015 4 Figure 9-1.

Device States Power Consumption1 Device State VDDIO IVBATT IVDDIO ON_Transmit VDDIO On 230mA @ 18dBm 29mA ON_Receive VDDIO On 68mA 29mA ON_Doze VDDIO On 280A <10A Power_Down GND On <0.5A <0.2A Note: 9.2.3 CHIP_EN 1. Conditions: VBAT @ 3.6v, IO@1.8V Restrictions for Power States When no power supplied to the device, i.e., the DC/DC Converter output and VDDIO are both off (at ground potential). In this case, a voltage cannot be applied to the device pins because each pin contains an ESD diode from the pin to supply. This diode will turn on when 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 SLEEP or 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. 9.3 Power-Up/Down Sequence The power-up/down sequence for ATWILC1000A is shown in Figure 9-2. The timing parameters are provided in Table 9-3. 26 ATWILC1000A-MUT [DATASHEET] 2 Atmel-42351C-ATWILC1000A-MUT-SmartConnect-Datasheet_022015 6 Figure 9-2.
