♠ Multiprotocol wireless 32-bit MCU Arm®-based Cortex®-M4 with FPU, Bluetooth® 5.2 radio solution
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 5.2. 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.
Enhanced inter-processor communication is provided by the IPCC with six bidirectional channels. The HSEM provides hardware semaphores used to share common resources between the two processors.
The device embeds high-speed memories (320 Kbytes of Flash memory, 48 Kbytes of SRAM) and an extensive range of enhanced I/Os and peripherals.
Direct data transfer between memory and peripherals and from memory to memory is supported by seven DMA channels with a full flexible channel mapping by the DMAMUX peripheral.
The device feature several mechanisms for embedded Flash memory and SRAM: readout protection, write protection and proprietary code readout protection. Portions of the memory can be secured for Cortex® -M0+ exclusive access.
