The STM32WB55 microcontroller (MCU) at the heart of these modules integrates a 2.4GHz RF transceiver supporting Bluetooth 5 (including BLE), Thread, and ZigBee stacks. Its dual Arm Cortex-M core architecture enables real-time secure application performance running on the 64MHz Cortex-M4F core, while concurrently managing the radio subsystem and security tasks on the co-integrated and completely independent Cortex-M0+.
