Add Support for Silicon Labs EFR32ZG23

Feb 13, 2026

With the release of Cyclone software v11.68 and PROG-HL-ARM software v9.94, PEmicro development and production programmers now support the Silicon Labs EFR32ZG23 microcontrollers.


The EFR32ZG23 MCU contains a High-Performance 32-bit 78 MHz ARM Cortex®-M33 with up to 512 KB of flash program memory. While the EFR32ZG23 devices are the ideal solution for Z-Wave, they can also support other protocols including Wi-SUN, Amazon Sidewalk, and Wireless M-BUS IoT applications. The single die, multi-core solution, provides industry leading security, low power consumption with fast wakeup times, and an integrated power amplifier to enable the next generation of secure connectivity for IoT devices.
