WF200SDR

The Silicon Labs WF200 is an Ultra Low Power Wi-Fi® transceiver or network co-processor (NCP) 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 WF200 integrates the Balun, T/R switch, LNA and PA for best possible RF performance. Co-existence with other external 2.4GHz radios is supported.
WF200 has been optimized for resource and power constrained devices at the RF, protocol, and firmware levels. Power conscious devices can take advantage of these features in both active and sleep modes.
For security sensitive applications, WF200 provides secure boot and a secure & encrypted host interface. Robust security is made possible with a native integrated True Random Number Generator and OTP memory for confidential encryption key storage.
The WF200 fits well with Linux-based and RTOS-based host processors. WF200 supports both the 802.11 lower MAC and the 802.11 full MAC architectures. It communicates with the external host controller over the SPI or SDIO interface.
