The STM32WBA52CEU6 multiprotocol wireless and ultra-low-power device embeds a powerful ultra-low-power radio compliant with Bluetooth® SIG Low Energy specification 5.3. They contain a high-performance Arm Cortex-M33 32-bit RISC core. They operate at a frequency of up to 100 MHz.

STM32WBA52CEU6 These devices integrate a 2.4 GHz RADIO that supports Bluetooth Low Energy and enables the use of proprietary protocols. The Cortex-M33 core features a single-precision floating-point unit (FPU) that supports all Arm single-precision data processing instructions and all data types. The Cortex-M33 core also implements a full set of DSP (Digital Signal Processing) instructions and a Memory Protection Unit (MPU) for enhanced application security.

STM32WBA52CEU6 These devices embed high-speed memory (up to 1 MB Flash and up to 128 KB SRAM), extensive enhanced I/O and peripherals connected to the AHB and APB buses on a 32-bit multi-AHB bus matrix. These devices provide compliance with TBSA (Trusted Secure Arm-Based Architecture) requirements. It embeds necessary security features to implement secure boot, secure data storage and secure firmware updates. In addition to these features, the device includes a secure firmware installation feature that allows customers to ensure the supply of code during their production. Flexible lifetime thanks to multi-level readout protection and unlocking for commissioning with a password.
