FG23 Wireless Sub GHz So C, First Look

Welcome to First Look, brought to you by DigiKey and Silicon Labs. Silicon Labs FG23 is the industrys first wireless subGHz SoC with an Arm CortexM33, a dedicated security core and Arm PSA3 certification. The EFR32FG23 product family combines an energyfriendly microcontroller, up to 512 kbytes of flash, and 64 kbytes of RAM with a high performance radio transceiver and integrated power amplifier with up to 20 dBm of transmit power. All of this includes a robust set of peripherals with up to 31 GPIO for easy prototyping. The highperformance subGHz radio provides long range and is not susceptible to 2. 4 GHz interference from technologies like WiFi. This radio can operate with a number of support modulation formats and protocols for both custom and standard subGHz communications. The high performance receiver offers sensitivities ranging from 98. 6 dBm to 110. 7 dBm depending on the modulation format and carrier frequency. While transmit power can go as high at 20 dBm with a transmit current of 85. 5 m
