STMicroelectronics STM32WB55VCQ6, 32 bit, STM32WB55VC Wireless Microcontroller, 64 MHz, 256kB FLASH, 129-Pin UFBGA

The STMicroelectronics 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 v5.0 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 that enhances application security.
