STMicroelectronics STM32WB15CCU6

The STM32WB15CC multiprotocol wireless and ultra-low-power device embeds a powerful and ultra-low-power radio compliant with the Bluetooth^® Low Energy SIG specification 5.3. 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 MPU.  and multi-protocols.

The STM32CubeWB package includes the STM32Cube hardware abstraction layer (HAL) and low-layer (LL) APIs peripheral drivers, a consistent set of middleware components (RTOS, USB, FatFS and STM32 touch sensing), as well as Bluetooth^® LE 5.3, OpenThread and Zigbee 3.0 connectivity stacks. All embedded software components come with a full set of examples running on STMicroelectronics boards.
