Arm Cordio-C50 radio IP is a complete self-contained radio sub-system supporting Bluetooth 5 and IEEE 802.15.4 protocols 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 and MAC controller along with link and MAC layer firmware. The RF front end is delivered as a hard macro, the digital parts delivered as RTL, and link and MAC 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 improved time to market.


Complete self-contained radio sub-system from RF to stack, supporting Bluetooth 5 and IEEE 802.15.4 protocols available at TSMC 55nm LP/ULP, TSMC 40nm LP/ULP, and UMC 55nm ULP process nodes
