Description
General part information
STM32WB55RC Series
The STM32WB55xx and STM32WB35xx multiprotocol wireless and ultra-low-power devices embed a powerful and ultra-low-power radio compliant with the Bluetooth®Low Energy SIG specification 5.4 and with IEEE 802.15.4-2011. They contain a dedicated Arm®Cortex®-M0+ for performing all the real-time low layer operation.
The devices are designed to be extremely low-power and are 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.
