STM32L431RCT6 MCU Description
The STM32L431RCT6 microcontroller is an ultra-low-power microcontroller based on the high-performance Arm? Cortex?-M4 32-bit RISC core, which operates at up to 80 MHz. All Arm? single-precision data-processing commands and data formats are supported by the Cortex-M4 core's Floating point unit (FPU) single precision. It also includes a memory protection unit (MPU) and a full set of DSP commands to improve application security. High-speed memories (Flash memory up to 256 Kbyte, 64 Kbyte of SRAM) are embedded in the STM32L431xx devices, as well as a Quad SPI flash memories interface (available on all packages) and a wide range of enhanced I/Os and peripherals connected to two APB buses, two AHB buses, and a 32-bit multi-AHB bus matrix.
