Description

Microchip's SmartConnect ATWILC1000 is an IEEE 802.11 b/g/n IoT link controller IC. The ATWILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, FPGAs and other processors with minimal resource requirements and a simple SPI/SDIO-to-Wi-Fi interface. The ATWILC1000 supports single stream 1x1 802.11n mode providing tested throughput of up to 46 Mbps UDP & 28 Mbps TCP/IP. The ATWILC1000 features a fully integrated Power Amplifier, LNA, Switch and Power Management. The only external clock source needed is a high-speed crystal or oscillator. The ATWILC1000 can be used in Linux, RTOS or Baremetal Environments. **The ATWILC1000 driver is part of the Mainline Linux Kernel beginning in version 5.9 found at Linux.org in the Kernel mainline under driver/net/wireless/microchip.** The WILC1000 Linux driver development is now an integrated development under the [Linux4sam.org](https://linux4sam.org/bin/view/Linux4SAM) project. The current stable release can be found at [github.com/linux4sam/linux-at91/tree/master/drivers/staging/wilc1000](https://github.com/linux4sam/linux-at91/tree/master/drivers/staging/wilc1000). The current development branch can be found at <https://github.com/linux4sam/linux-at91/tree/linux-5.10-at91/drivers/net/wireless/microchip> The WILC demo, serial bridge and firmware are hosted at [github.com/linux4wilc](https://github.com/linux4wilc) Microchip's complimentary and confidential [Wireless Check online design review service](https://www.microchip.com/en-us/support/design-help/design-check-services) is available for customers who have selected our products for their application design-in\*. \*The online design review service is subject to Microchip's [Program Terms and Conditions](https://www.microchip.com/en-us/support/design-help/design-check-services/design-check-services-program-terms-and-conditions) and requires a myMicrochip account.
