EFR32MG21 - Multiprotocol Wireless SoC (Matter/Zigbee/Thread)
EFR32MG21
The Mighty Gecko multiprotocol family of SoCs is part of the Wireless Gecko portfolio. Mighty Gecko SoCs are ideal for enabling energy-friendly multiprotocol, multiband networking for IoT devices.
DescriptionSpecificationNews/ArticlesData Sheet
EFR32MG21 devices bring high performance, low power and secure solutions to the IoT. Designed to increase processing capability, improve RF performance and lower active current, EFR32MG21 devices are 2.4 GHz wireless SoCs optimized for line-powered Zigbee, Thread and Bluetooth mesh applications, including connected lighting, gateways, voice assistants and smart metering.
The EFR32MG21 family of SoCs includes an integrated security subsystem and devices that can take advantage of Secure Vault technologies. Secure Vault delivers leading security software features with physically unclonable function (PUF) hardware technology to greatly reduce the risk of IoT security breaches and compromised intellectual property.
With better than -104 dBm sensitivity for both 802.15.4 and Bluetooth Long Range and up to +20 dBm output power, EFR32MG21 provides a robust RF link to ensure reliable communications. EFR32MG21 uses Simplicity Studio 5 development tools, providing easy migration and fast time-to-market with development kits, SDKs, mobile apps and our patented network analyzer.
EFR32MG21 applications include:
