The Arm Cordio-B50 radio IP is a complete self-contained radio subsystem supporting Bluetooth 5 protocol available at TSMC 55nm LP/ULP, TSMC 40nm LP/ULP and UMC 55nm ULP process nodes. The solution consists of the RF 2.4GHz transceiver, modem, protocol processing logic and link controller along with link layer firmware. The RF front end is delivered as a hard macro, the digital bits delivered as RTL, and link layer firmware as source code. The design is optimized for low-power end node IoT devices and enables designers who want a silicon proven and qualified/certified solution for reduced risk and reduced time to market.
