With key features like high-performance 2.4 GHz RF, low current consumption, an AI/ML hardware accelerator, and Secure Vault™, IoT device makers can create the smart, robust, and energy-efficient products that are secure from remote and local cyber-attacks. An ARM Cortex®-M33 running up to 78 MHz and up to 3 MB of flash and 512 kB of RAM enables more complex applications and provides headroom for Matter over Thread. Target applications include gateways and hubs, LED lighting, switches, sensors, locks, glass break detection, predictive maintenance, wake-word detection, and more.

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 -104.3 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.
