ATWILC1000-IC

In Production

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 dr...

  • 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 project.

    The current stable release can be found at 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
