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.

EFR32BG22 and EFR32BG22E Bluetooth low energy (LE) wireless SoC solutions are part of the Wireless Gecko Series 2 platform. These devices are designed with a strong focus on energy efficiency, offering best-in-class ultra-low transmit and receive power, and a high-performance, low-power Arm® Cortex®-M33 core delivers industry-leading energy efficiency that can extend coin cell battery life up to ten years. Where BG22 allows you to create energy-efficient applications, the BG22E – ‘E’ denoting Energy Conservation – takes this a step further by enhancing battery longevity and supporting designs that eliminate the need for batteries altogether. Our BG22 and BG22E family's are the ideal market leading SoCs for Ambient IoT or Energy Harvesting devices. Target applications include Bluetooth mesh low-power nodes, smart door locks, personal healthcare and fitness devices. Asset tracking tags, beacons and indoor navigation also benefit from the SoCs' versatile Bluetooth Angle of Arrival (AoA) and Angle of Departure (AoD) capabilities and sub-one-meter location accuracy.

EFR32FG22 and EFR32FG22E proprietary wireless 2.4 GHz SoC solutions are part of the Wireless Gecko Series 2 platform. FG22 SoCs integrate a 38.4 MHz Arm® Cortex®-M33 core with TrustZone and a high-performance radio with a receive sensitivity of -102.3 dBm. Where FG22 allows you to create energy-efficient applications, the FG22E – ‘E’ denoting Energy Conservation – takes this a step further by enhancing battery longevity and supporting designs that eliminate the need for batteries altogether. The SoC's combination of ultra-low transmit and receive power (8.2 mA TX at +6 dBm, 3.6 mA RX), 1.2 µA deep-sleep mode power and innovative low-power features such as RFSense delivers industry-leading energy efficiency to extend the operational life of products with limited battery or energy harvesting options such as those used by electronic shelf labels and industrial wireless sensor nodes.
