EFR32BG21 (BG21) - Bluetooth Wireless SoC
EFR32BG21
The Blue Gecko family of SoCs is part of the Wireless Gecko portfolio. Blue Gecko SoCs are ideal for enabling energy-friendly Bluetooth 5 networking for IoT devices.
DescriptionSpecificationsNews/ArticlesData Sheet
Wireless Gecko Series 2 devices are the next evolution of Wireless Gecko devices bringing high performance, low power, and secure solutions to the Internet of Things. Designed to increase processing capability, improve RF performance and lower active current, the devices also provide the highest level of IoT device security. The EFR32BG21 devices are also designed to support Silicon Labs' enhanced security option, Secure Vault.
EFR32BG21 devices are 2.4 GHz wireless SOCs optimized for line-powered Bluetooth Low Energy and Bluetooth mesh applications, including connected lighting, smart plugs, gateways and voice assistants. An 80 MHz ARM® Cortex®-M33 core provides plenty of processing capability while an integrated security subsystem provides leading security features that greatly reduce the risk of IoT security breaches and compromised intellectual property. With better than -104.3 dBm sensitivity and up to +20 dBm output power, the EFR32BG21 family uses Simplicity Studio 5 development tools, providing easy migration and fast time-to-market with development kits, SDKs, mobile apps, our energy profiler and patented network analyzer.
Blue Gecko applications include:
