The device features 1 MB of dual-bank Flash memory supporting read-while-write operation and 256 KB of SRAM, providing ample resources for complex wireless protocol stacks and application code. The integrated 2.4 GHz radio transceiver supports Bluetooth Low Energy 5.3, IEEE 802.15.4 (for Thread and Zigbee 3.0), and concurrent multi-protocol operation. An integrated SMPS step-down converter reduces current consumption to just 7.8 mA at +6 dBm output power, while standby current drops to 600 nA with RTC and 32 KB RAM retention. Security features include AES-256 hardware encryption, a public key accelerator (PKA), and a true random number generator. The TR suffix indicates tape and reel packaging for automated assembly.","working_principle":"The STM32WB55CGU6TR operates through five integrated subsystems: (1) The Cortex-M4 (CPU1) runs the application code at up to 64 MHz with FPU for DSP operations, accessing Flash and SRAM via the multi-AHB bus matrix. It communicates with the radio coprocessor through the IPCC (Inter-Processor Communication Controller) using a standardized API. (2) The Cortex-M0+ (CPU2) executes the BLE and 802.15.4 radio stack independently, handling all real-time protocol timing, link layer operations, and RF control without intervention from CPU1. This dual-core architecture ensures deterministic radio behavior while freeing CPU1 for application tasks. (3) The RF subsystem integrates the 2.4 GHz transceiver with a built-in balun, programmable output power up to +6 dBm, and high sensitivity of -100 dBm for 802.15.4. The SMPS step-down converter powers the RF PA efficiently. (4) The analog peripheral block includes a 12-bit ADC at 4.26 MSPS, two ultra-low-power comparators, and capacitive touch sensing. (5) The power management system provides multiple low-power modes with fast wakeup, down to 600 nA in standby mode.","pin_description":"
