2.4 GHz and Dual Band Devices

The EFR32™ Flex Gecko family of wireless SoCs combines an energy-friendly MCU with a highly integrated radio transceiver supporting 2.4 GHz and Sub-GHz proprietary wireless protocols. The single-die solution provides industry-leading energy efficiency, ultra-fast wakeup times, a scalable power amplifier, and an integrated balun. The devices are supported with SDKs including an intuitive radio abstraction interface layer (RAIL) and Connect Stack to accelerate proprietary protocol development.
