STM32WB55REV6

STM32WB55REV6 is a multiprotocol wireless 32bit MCU Arm®-based Cortex®-M4 with FPU. This 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 and with IEEE 802.15.4-2011. It contains a dedicated Arm® Cortex®-M0+ for performing all the real-time low-layer operations. 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 64MHz. 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.
