Overview

The EFR32MG21A010F1024IM32-BR is a Mighty Gecko Series 2 wireless SoC designed for mesh networking. It integrates a 2.4 GHz radio with 10 dBm output power and 1024 kB of flash memory to support complex multiprotocol applications including Zigbee, Thread, and Bluetooth mesh.

Why Choose This Part

This SoC features a dedicated security core for hardware-accelerated cryptography and secure boot. With 1024 kB of flash and 96 kB of RAM, it provides ample headroom for concurrent multiprotocol operations and over-the-air (OTA) updates.

Applications

Smart Home Hubs
Serves as the central controller for Zigbee and Thread ecosystems, managing large device networks.
Connected Lighting
Enables mesh-capable wireless control for LED drivers and luminaires with high temperature reliability.
Building Automation
Powers sensors and actuators within commercial building management systems using robust mesh protocols.

Getting Started

Develop using the Simplicity Studio 5 IDE which provides the Gecko SDK and network analyzer tools. For hardware evaluation, the SLWSTK6006A Wireless Starter Kit is the standard platform for Series 2 development.
