STMICROELECTRONICS STM32WBA54CGU6 ARM MCU, STM32 Family STM32WB Series STM32WBA54xx Group Microcontrollers, ARM Cortex-M33F, 32 bit

STM32WBA54CGU6 is an Arm® based 32-bit microcontroller. It is a multiprotocol wireless and ultra-low power device embeds a powerful and ultra-low power radio compliant with the Bluetooth® SIG Low Energy specification 5.4. The device integrates a 2.4GHz RADIO supporting Bluetooth low energy, and makes possible to use proprietary protocols. It is based on a high-performance Arm Cortex-M33 32-bit RISC core, featuring a single-precision floating-point unit (FPU), supporting all the Arm single-precision data-processing instructions and all the data types. This core also implements a full set of DSP (digital signal processing) instructions and a memory protection unit (MPU) that enhances the application security. The device offers security foundation compliant with the TBSA (trusted-based security architecture) requirements from Arm. It embeds the necessary security features to implement a secure boot, secure data storage, and secure firmware update.
