WF200 Wi-Fi Transceiver IC

Silicon Labs' WF200 is the perfect Wi-Fi transceiver for a user's secure, low-power IoT Wi-Fi needs. The Wi-Fi transceiver contains a 2.4 GHz 802.11 b/g/n radio (MAC and PHY layer) that is optimized for low power and optimal RF performance in crowded RF environments. It supports both Linux-based hosts and RTOS-based hosts to deliver a complete Wi-Fi solution. High-speed (serial peripheral) SPI and secure digital input-output (SDIO) host interfaces provide flexibility throughout.

The encrypted secure link interface ensures that communication between the host processor and the WF200S are always protected to secure a user's data, service set identifier (SSID), and passwords.
