The STM32L431RCT6TR devices are ultra-low-power microcontrollers built around the powerful 32-bit RISC Arm? Cortex?-M4 core that can operate at up to 80 MHz. A floating point unit (FPU) single precision is a characteristic of the Cortex-M4 core that supports all Arm? single-precision data-processing instructions and data formats. Additionally, it incorporates a memory protection unit (MPU) that improves program security together with the whole range of DSP instructions.
