Atmel ATWILC1500-MR [PRELIMINARY DATASHEET]

Atmel-42376A-ATWINC1500-MR210P-SmartConnect-Datasheet_102014

4 RESET_N I

Active-Low Hard Reset. When asserted to a low level, the module will be

placed in a reset state. When asserted to a high level, the module will run

normally. Connect to a host output that defaults low at power up. If the host

output is tri-stated, add a 1M pull-down resistor to ensure a low level at

power up.

5 NC - No connect

6 NC - No connect

7 NC - No connect

8 NC - No connect

9 GND_1 - GND

10 SPI_CFG I Tie to VDDIO through a 1M resistor to enable the SPI interface NO

11 WAKE I

Host Wake control. Can be used to wake up the module from Doze mode.

Connect to a host GPIO.

12 GND_2 - GND

13 IRQN O

ATWINC1500-MR210PA Device Interrupt output. Connect to host interrupt

input pin.

14 UART_TXD O UART Transmit Output from ATWINC1500-MR210P YES

15 SPI_RXD I SPI MOSI (Master Out Slave In) pin YES

16 SPI_SSN I SPI Slave Select. Active low YES

17 SPI_TXD O SPI MISO (Master In Slave Out) pin YES

18 SPI_CLK I SPI Clock YES

19 UART_RXD I UART Receive input to ATWINC1500-MR210P YES

20 VBATT - Battery power supply

21 GPIO_1 I General Purpose I/O YES

22 CHIP_EN I

Module enable. High level enables module, low level places module in

Power Down mode. Connect to a host Output that defaults low at power up.

If the host output is tri-stated, add a 1M ohm pull-down resistor to ensure a

low level at power up.

23 VDDIO - I/O Power Supply. Must match host I/O voltage

24 1P3V_TP - 1.3V VDD Core Test Point. Leave unconnected

25 NC - No connect

26 GPIO_15 I/O General purpose I/O YES

27 GPIO_16 I/O General purpose I/O YES

28 GND_3 - GND
