Silicon Labs FG28 Sub-GHz wireless and 2.4 GHz BLE SoC supports Amazon Sidewalk, Wi-SUN, etc…

Silicon Labs dual-band FG28 Cortex-M33 SoC comes with sub-Gigahertz and 2.4 GHz Bluetooth LE radios that support long-range networks and protocols like Amazon Sidewalk, Wi-SUN, and other proprietary protocols, as well as a built-in AI/ML accelerator for machine learning inference and SiLabs Secure Vault technology. The chip looks to be an update to the sub-GHz FG25 Cortex-M33 microcontroller with an additional 2.4 GHz BLE radio, but somehow less program memory (up to 256KB) and storage (up to 1024 KB). The peripherals implemented in the chip are almost the same, as the microcontroller gains support for predictive maintenance with a small matrix vector processor for AI/ML acceleration. Silicon Labs FG28 (EFR32FG28) specifications: MCU core – Arm Cortex-M33 @ 78 MHz with DSP instructions and FPU On-chip memory – Up to 256 kB RAM data memory On-chip storage – Up to 1024 kB flash program memory AI accelerator – Matrix Vector Processor […]
