Silicon Labs WFM200SS22XNN3 1.8 → 3.3V WiFi Module, IEEE 802.11 b/g/n SDIO, SPI

The Silicon Labs ultra low power Wi-Fi transceiver or network co-processor (NCP) SiP module targeted for applications where optimal RF performance, low power consumption, and secure end-to-end solution, together with fast time to market, are key requirements. The very compact 6.5mm x 6.5mm WFM200S SiP module contains an embedded antenna, high frequency crystal, and shield. This all-inclusive module offer the fastest time to market. The WFM200S fits well with Linux-based and RTOS-based host processors. WFM200S supports both the 802.11 split MAC architecture and the 802.11 full MAC software architecture. WFM200S communicates with the external host controller over the SPI or SDIO interface.
