8.5 Interfacing with a Wireless Module

To interface the SAM9X60D1G-I/LZB System-On-Module with a wireless feature, several interfaces must be used, such as SDIO and USART interfaces. The example below is a Microchip ATWILC3000 wireless module.

ATWILC3000 is a single chip IEEE® 802.11 b/g/n RF/Baseband/MAC link controller with integrated Bluetooth® 5.0. The ATWILC3000 connects to Microchip AVR/SMART MCUs, SMART MPUs and other processors with minimal resource requirements using simple SPI/SDIO-to-Wi-Fi® and UART-to-Bluetooth interfaces. Any of the two ATWILC3000 variants, ATWILC3000-MR110UA (u.FL connector) and ATWILC3000-MR110CA (integrated antenna), can be used.
