WF200 Series 2 Wi-Fi Transceiver IC

WF200 devices are the perfect Wi-Fi transceivers for secure, low-power IoT Wi-Fi applications. The transceiver is a 2.4 GHz 802.11b/g/n radio (MAC and PHY layer), optimized for low power and optimal RF performance in crowded RF environments, supporting Linux-based and RTOS-based hosts to deliver a complete Wi-Fi solution. High speed SPI and SDIO host interfaces provide flexibility and throughput, and an optional secure link interface between the host and the transceiver enhance security.
