Overview

The EFR32MG21B010F512IM32-B is a high-performance Mighty Gecko Series 2 SoC designed for multiprotocol mesh networking. It features a 2.4 GHz radio with 10 dBm output power and 512 kB of flash memory, optimized for Zigbee, Thread, and Bluetooth mesh applications.

Why Choose This Part

This SoC includes a dedicated security core (Secure Vault) for hardware-accelerated cryptography and secure boot. Its Series 2 architecture delivers significantly lower active current and higher processing efficiency compared to previous generations, extending battery life in constrained environments.

Applications

Smart Home Lighting
Provides reliable mesh connectivity for connected bulbs and light switches using Zigbee or Thread.
Building Automation
Acts as a wireless node for HVAC controls and occupancy sensors in large-scale commercial networks.
IoT Gateways
Serves as a multiprotocol radio co-processor in hub devices that must bridge various wireless standards.

Getting Started

Engineers should use the Simplicity Studio IDE and the Gecko SDK (GSDK) for firmware development. The SLWSTK6006A Wireless Starter Kit is the recommended hardware platform for evaluating the 2.4 GHz radio performance and mesh networking stacks.
