STM32L431CBT6 Microcontroller MCU Ultra-Low-Power ARM Cortex-M4 32-Bit 80MHz MCU

Product Description Of STM32L431CBT6
STM32L431CBT6 is the ultra-low-power microcontrollers based on the high-performance Arm® Cortex®-M4 32-bit RISC core operating at a frequency of up to 80 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which 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) which enhances application security.
