4.2 WINC1500-XPRO Peripherals

ATWINC15x0-MR210xB Control Signals

The ATWINC15x0-MR210xB main control pins are connected to the Xplained Pro extension header. SPI is the only host interface.

LED

There is one dual green/red LED on the Xplained Pro extension board that is controlled by the ATWINC15x0-MR210xB. These LEDs are used to show application status.

Crypto Device

The WINC1500-XPRO features a CryptoAuthentication™ device (ATECC508A). The same I²C interface lines are shared between the two Client devices (WINC1500 module and crypto device). Host MCU from the Xplained Pro MCU board will be the Host for this I²C. I²C connections of the wireless module with the host can be separated by removing R107 and R108 for communication between crypto device and MCU. If there is any issue in this communication, it is recommended that pull-up resistors R104 and R105 be mounted.
