The new Wireless Gecko system-on-chip (SoC) family from Silicon Labs

     The new Wireless Gecko system-on-chip (SoC) family from Silicon Labs. This family of SOCs offers superior energy efficiency and battery life for a variety of Internet of Things (IoT) applications.

     The Silicon Labs EFR32BG22 (BG22) SoC is a single-chip solution that supports Bluetooth 5.2 connectivity including Bluetooth Mesh, Bluetooth Low Energy, and direction finding with submeter accuracy. These versatile SOCs extend the life of button batteries to up to 10 years, making them energy efficient choices for consumer, commercial and industrial iot applications. The EFR32BG22 SoC is powered by a high-performance Arm® Cortex®-M33 core and offers ultra-low transmit and receive power consumption.

     The EFR32MG22 (MG22) family of devices is an ultra-small, ultra-low power SoC optimized for Zigbee green power applications. The MG22 SoC combines a 76.8 MHz Arm Cortex-M33 core with a high-performance 2.4 GHz radio that supports multiple IoT protocols. These energy-efficient SOCs are ideal for Zigbee devices used to power button batteries or energy harvesting devices, including smart home sensors, lighting control devices, and building and industrial automation.

     The EFR32FG22 (FG22) SoC enables energy-efficient proprietary protocol networks in power - and size-constrained iot devices. The single-chip device uses a 38.4 MHz Arm Cortex-M33 processor and a 2.4 GHz radio with a receive sensitivity of -106.4 dBm. With advanced security features and a full suite of software tools and protocol stacks, the FG22 SoC is ideal for applications such as building security, electronic shelf labels, industrial automation sensors, and custom modules for commercial lighting.
