Microchip's SmartConnect ATWILC1000 is an 802.11 b/g/n IoT link controller module. The ATWILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, and other processors with minimal resource requirements with 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.
