ATWILC1000 IEEE Wi-Fi Controller

Microchip's SmartConnect ATWILC1000 is an IEE 802.11 IoT link controller module

Image of Microchip's ATWILC1000 IEEE WiFi ControllerThe ATWILC1000 from Microchip Technology is an IEEE 802.11 b/g/n IoT link controller modules. It is the ideal add-on to existing MCU solutions bringing Wi-Fi through SPI/SDIO-to-Wi-Fi interface. It connects to any Microchip AVR or SMART MCU with minimal resource requirements. The ATWILC1000's most advanced mode is a single stream 1x1 802.11n mode providing up to 72 Mbps PHY throughput. It features fully integrated power amplifier (PA), low noise amplifier (LNA), switch, and power management. The only external clock source needed for the ATWILC1000 is a high-speed crystal or oscillator with a wide variety of reference clock frequencies supported. The module is specifically optimized for low power IoT applications. It features small form factor (21.7 mm x 14.7 mm x 2.1 mm) while fully integrating PA, LNA, transmit/receive (T/R), switch, power management, and PCB antenna. With advanced security, it is interoperable with various vendors using IEEE 802.11 b/g/n access points in wireless LAN. The module provides serial peripheral interface (SPI) and secure digital input output (SDIO) to interface with the host controller.
