STMicroelectronics STM32WB35CEU7A, 32 bit ARM Cortex M0+, ARM Cortex M4, STM32WB, 64 MHz, 512kB FLASH, 48-Pin UFQFPN

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
• The Cortex®-M4 core features a Floating point unit (FPU) single precision
• Implements a full set of DSP instructions and a memory protection unit (MPU) that enhances application security
