EFR32FG22 Proprietary Wireless 2.4 GHz SoC

OVERVIEW
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 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 delivers 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.
