EFR32MR21 2.4GHz Wireless ICs

Silicon Labs EFR32MR21 2.4GHz Wireless ICs are optimized for adding Zigbee®, Thread, or BLUETOOTH® for gateway, hubs, and voice assistants. The EFR32MR21 is an RCP (Radio Co-Processor) that runs the PHY and MAC only, while the rest of the network layer, protocol, and application run on a separate host MPU.
