WF200 Wi-Fi® Transceiver

The Perfect Wi-Fi Transceiver IC for IoT Applications

The WF200 is the perfect Wi-Fi transceiver for your secure, low power IoT Wi-Fi needs. The Wi-Fi transceiver contains 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. The device supports both linux-based hosts and RTOS-based hosts to deliver a complete Wi-Fi solution. High speed SPI and SDIO host interfaces provide flexibility and throughput.

Use WF200S for a secure link interface between the host and the transceiver.
