EFR32MR21A020F512IM32

Zigbee*, Thread, and Bluetooth Radio Co-Processor (RCP)

The EFR32MR21A020F512IM32 is a wireless RCP (Radio Co-Processor) device that has been optimized for gateways, hubs, and access points. Based on the MG21 family, the MR21 runs the PHY/MAC for 802.15.4 and up to the HCI interface for Bluetooth Low Energy. For products that already have a separate host MCU or MPU, the RCP device enables lower hardware cost by reducing the requirements of the wireless IC and allowing the wireless protocol and application to run on the existing host MCU/MPU. The MR21 device includes 512 Flash, 64 RAM and is available in a QFN32 package. With +20 dBm maximum power output and excellent receive sensitivity the EFR32MR21A020F512IM32 provides a robust RF link for reliable communications.

*Zigbee requires a separate Zigbee software license fee for the EFR32MR21
