EFR32FG22 Series 2 Proprietary Wireless 2.4 GHz SoC

Silicon Labs delivers a 2.4 GHz proprietary wireless solution for electronic shelf labels, smart lighting, and building automation

Image of Silicon Labs' EFR32FG22 Series 2 Proprietary Wireless 2.4 GHz SoC Silicon Labs' EFR32FG22 (FG22) 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.

The EFR32FG22 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, deliver 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.

Features
  • 32-bit Arm Cortex-M33 core with 38.4 MHz maximum operating frequency
  • Up to 512 KB of Flash and 32 KB of RAM
  • Energy-efficient radio core with low active and sleep currents
  • Integrated PA with up to 6 dBm (2.4 GHz) TX power
  • Secure Boot with Root of Trust and Secure Loader (RTSL)
  • RFSENSE with selective OOK mode
Applications
  • Electronic shelf labels
  • Home and building automation and security
  • Industrial automation
  • Commercial and retail lighting and sensing
