Silicon Labs released new EFR32FG22 (FG22) proprietary wireless system-on-chip (SoC) devices designed for power- and size-constrained IoT products powered by batteries or energy harvesting sources. 

The FG22 integrates a 38.4 MHz Arm® Cortex®-M33 core with TrustZone and a high-performance radio with a receive sensitivity of -106.4 dBm. The SoCs’ combination of ultra-low transmit and receive power (8.2 mA TX at +6 dBm, 3.6 mA RX) and 1.2 µA deep-sleep mode power delivers exceptional energy efficiency. Additional low-power on-chip features such as RFSense, which wakes the FG22 in the presence of RF energy, further extend the operating life of IoT products with limited battery or energy harvesting options.

Target applications include electronic shelf labels (ESL), building security, industrial automation sensors and custom modules for commercial lighting. Based on Silicon Labs’ Wireless Gecko Series 2 platform, the EFR32FG22 (FG22) SoCs deliver an optimal combination of security features, 2.4 GHz wireless performance, energy efficiency, and software tools and stacks to enable the next generation of ESL and pricing automation products.
