STMicroelectronics STM32WB15CCU6, 32 bit ARM Cortex M0+, ARM Cortex M4, STM32WB Microcontroller, 64 MHz, 320kB FLASH,

The STMicroelectronics STM32WB10CC multiprotocol wireless and ultra-low-power device embeds a powerful and ultra-low-power radio compliant with the Bluetooth Low Energy SIG specification 5.2. It contains a dedicated Arm Cortex-M0+ for performing all the real-time low layer operation. The device is designed to be extremely low-power and is based on the high-performance Arm Cortex-M4 32-bit RISC core operating at a frequency of up to 64 MHz. This core features a Floating point unit (FPU) single precision that supports all Arm single-precision data-processing instructions and data types. It also implements a full set of DSP instructions and a memory protection unit (MPU) that enhances application security.
