EFR32xG22 Wireless Gecko Reference Manual

2020-11-23 Silicon Labs User's Guide English
The EFR32xG22 Wireless Gecko SoC includes the EFR32BG22, EFR32FG22, and EFR32MG22 Wireless Gecko families. The EFR32xG22 improves processing capability with a Cortex M33 core, while providing for lower active current for both the MCU and radio. This low power and application optimized device supports Bluetooth 5.2 (including Direction Finding), Proprietary 2.4 GHz & Zigbee PRO/Green Power protocols.
The EFR32xG22 solution provides industry-leading energy efficiency, processing capa-bility, and RF performance in a small form factor for IoT connected applications.
This document contains reference material for the EFR32xG22 devices. All modules and peripherals in the EFR32xG22 devices are described in general terms. Not all modules are present in all devices and the feature set for each device might vary. Such differences,including pinout, are covered in the device data sheets.
KEY FEATURES:
● 32-bit ARM® Cortex M33 core with up to 76.8 MHz maximum operating frequency
● Scalable Memory and Radio configuration options available in QFN packaging
● Energy-efficient radio core with low active and sleep currents
● Secure Boot with Root of Trust and Secure Loader (RTSL)
● Integrated PA with up to 6 dBm transmit power
