controller SoC for Internet of Things (IoT) applications. This feature allows for the addition of Wi-Fi and

Bluetooth to an MPU/MCU application via an SDIO/SPI to Wi-Fi and UART to Bluetooth. The ATWILC*

family contains two flavors:

•ATWILC1000, which is a Wi-Fi only SoC

•ATWILC3000, which is Wi-Fi and Bluetooth/BLE SoC

Note:  All references to the ATWILC* module include ATWILC1000 and ATWILC3000, unless otherwise

noted.
