Added Support for Silicon Labs EFR32FG25 Microcontrollers

Sep 04, 2025

With the release of Cyclone software v11.63 and PROG v9.87, PEMicro’s development and production tools now include support for Silicon Labs EFR32FG25 Long Range Sub-GHz Wireless microcontrollers. The EFR32FG25 MCU is based on the ARM Cortex-M33 and designed for long range sub-GHz wireless connectivity for smart metering, lighting, city and building automation. Each EFR32FG25 device support includes two .ARP algorithms that target different regions of the flash memory. The main algorithm, for example SiliconLabs_EFR32FG25A111F1152_1152KB.arp, is used to program, erase and verify data in the main flash and user data regions at addresses 0x08000000 and 0x0FE00000 respectively. The second .ARP algorithm ends with …_DeviceInfo.arp and is used to verify the 1KB device information region at address 0x0FE08000.

New device support added for the following part numbers: EFR32FG25A111F1152IM56, EFR32FG25A121F1152IM56, EFR32FG25A211F1920IM56, EFR32FG25A221F1920IM56, EFR32FG25B111F1152IM56, EFR32FG25B121F1152IM56, EFR32FG25B211F1920IM56, EFR32FG25B212F1920IM56, EFR32FG25B221F1920IM56, EFR32FG25B222F1920IM56
