The STM32WB55CEU6 multiprotocol wireless and ultra-low-power device embeds a powerful ultra-low-power radio that complies with Bluetooth® LowEnergy SIG specification 5.2 and IEEE 802.15.4-2011. They contain a dedicated Arm®Cortex®-M0+ for all real-time low-level operations.

These devices consume very low power and are based on a high-performance Arm® Cortex®-M4 32-bit RISC core running at frequencies up to 64 MHz. The core features support for all Arm® floating-point unit (FPU) single-precision single-precision data processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) for enhanced application security.
