The STM32WB55CGU6 from STMicroelectronics is an ultra-low-power dual-core wireless microcontroller that combines a 64 MHz Cortex-M4 application processor with a dedicated 32 MHz Cortex-M0+ radio coprocessor in a 48-pin UFQFPN package. With 1 MB of dual-bank Flash and 256 KB SRAM, it provides ample resources for complex wireless protocol stacks and application code. The integrated 2.4 GHz radio supports Bluetooth Low Energy 5.3, IEEE 802.15.4 for Thread and Zigbee, and concurrent multi-protocol operation. The integrated SMPS reduces TX current to 7.8 mA at +6 dBm while standby current is only 600 nA with RTC. Security features include AES-256, PKA, and true RNG. This is the tube-packaged version suitable for prototyping and low-volume production, differing from the TR tape-and-reel variant only in packaging format.

The STM32WB55CGU6 operates through five integrated subsystems: (1) The Cortex-M4 (CPU1) executes application code at up to 64 MHz with FPU for DSP operations, communicating with the radio coprocessor via the IPCC using a standardized API. (2) The Cortex-M0+ (CPU2) independently runs the BLE and 802.15.4 radio stack, handling real-time protocol timing, link layer operations, and RF control without CPU1 intervention. (3) The RF subsystem integrates a 2.4 GHz transceiver with built-in balun, programmable output power up to +6 dBm, and sensitivity of -100 dBm for 802.15.4. The SMPS efficiently powers the RF PA. (4) The analog block includes a 12-bit ADC at 4.26 MSPS, two ultra-low-power comparators, and capacitive touch sensing up to 24 channels. (5) Power management provides multiple low-power modes with fast wakeup, down to 600 nA standby with RTC and 32 KB RAM retention.
