EFR32MG27 Wireless Gecko SoC Family
Data Sheet
The EFR32MG27 Wireless Gecko multiprotocol family of SoCs is
part of the Wireless Gecko portfolio. EFR32MG27 Wireless Gecko
KEY FEATURES
SoCs are ideal for enabling energy-friendly multiprotocol network-
ing for IoT devices.
• 32-bit ARM® Cortex®-M33 core with 76.8
MHz maximum operating frequency
• 768 kB of flash and 64 kB of RAM
The single-die solution combines a 76.8 MHz Cortex-M33 with a high performance 2.4
GHz radio to provide an industry-leading, energy efficient wireless, SoC for IoT connec-
ted applications.
• Energy-efficient radio core with low active
and sleep currents
• Integrated PA with up to 8 dBm (2.4 GHz)
TX power
The devices are available with boost or buck DC-DC capabilities, enabling direct power
from a wide variety of batteries.
• Secure Boot with Root of Trust and
Secure Loader (RTSL)
• Pin compatibility / feature superset with
EFR32xG22
Wireless Gecko applications include:
