WF200SD

WF200SD 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. It integrates the Balun, T/R switch, LNA and PA for best possible RF performance. Co-existence with other external 2.4GHz radios is supported. Power conscious devices can take advantage of these features in both active and sleep modes. For security sensitive applications, it provides secure boot and a secure and encrypted host interface. Robust security is made possible with a native integrated true random number generator and OTP memory for confidential encryption key storage. Typical applications are industrial, home and building automation, home appliances, security solutions, retail and commercial, commercial transportation, consumer medical, sports and fitness.
