Microchip Embedded Wi-Fi®




Microcip Embedded Wi-Fi® is a family of self-contained, low power and certified modules bringing wireless internet connectivity.

ATWILC1000 is IEEE 802.11 b/g/n/ IOT link controller utilizing highly optimized 802.11 and provides mulitple peripheral interfaces like SPI, and SDIO.

ATWILC3000 is IEEE 802.11 b/g/n/BT4.0 IOT link controller utilizing highly optimized 802.11-Bluetooth coexistence protocol and provides mulitple peripheral interfaces like UART, SPI, and SDIO.

This is the unified driver source for wilc1000 & wilc3000 chipsets.

Refer to the Wi-Fi Link Controller Linux User Guide for information on how to use the wireless devices on linux and the Wi-Fi Link Controller Linux Release Notes for the latest release notes and revision history.
