These new SoCs are highly energy efficient, delivering extended battery life for a range of Internet of Things (IoT) applications.
The EFR32BG22 (BG22) SoCs are single-chip solutions that support Bluetooth 5.2 connectivity, including Bluetooth Mesh, Bluetooth Low Energy, and direction-finding with sub-meter accuracy. The versatile SoCs are capable of extending coin cell battery life for up to ten years, making them a suitable choice for energy-friendly consumer, commercial, and industrial IoT applications. The EFR32BG22 SoCs are based on a high-performance Arm Cortex-M33 core and offer ultra-low transmit and receive power.
The EFR32MG22 (MG22) family devices are the smallest, lowest power SoCs optimised for Zigbee Green Power applications. Combining a 76.8 MHz Arm Cortex-M33 core with a high-performance 2.4 GHz radio, the MG22 SoCs can support multiple IoT protocols. The energy-efficient SoCs are intended for Zigbee devices powered by coin cell batteries or energy-harvesting sources, including smart home sensors, lighting controls, and building and industrial automation.
The EFR32FG22 (FG22) SoCs enable energy-friendly proprietary protocol networking in power- and size-constrained IoT devices. The single-die devices feature a 38.4 MHz Arm Cortex-M33 processor and a 2.4 GHz radio with a receive sensitivity of -106.4 dBm.
The FG22 SoCs provide advanced security features and a comprehensive suite of software tools and stacks, making them a suitable option for applications such as building security, electronic shelf labels, industrial automation sensors, and custom modules for commercial lighting.
