Description

The STM32WB35CCU7A multi-protocol wireless and ultra-low-power devices embed a powerful ultra-low-power radio that complies with the Bluetooth BLE SIG specification 5.4 and the IEEE 802.15.4-2011. They contain a dedicated processing Arm® Cortex®-M4 device that performs all the real-time, low-level operations.

The devices are based on the high-performance Arm® Cortex®-M4 32-bit RISC core, which operates at up to 64 MHz with very low power consumption. The core features a single-precision floating-point unit (FPU) that supports all Arm® single-precision data processing instructions and data types. It also implements a full suite of DSP instructions and a Memory Protection Unit (MPU) for increased application security.
