STM32L431RCT6 ST Microcontroller

STM32L431RCT6 is an ultra-low-power 32-bit microcontroller from STMicroelectronics, based on the Arm Cortex-M4 core with FPU (Floating Point Unit) running at up to 80MHz. It features 256KB of Flash memory with ECC support and 64KB of SRAM (including 16KB with hardware parity check), providing robust storage for embedded applications. The device achieves exceptional energy efficiency with multiple low-power modes including Shutdown (8nA), Standby (28nA), and Stop 2 (1.0µA), making it ideal for battery-powered applications. It integrates a fast 12-bit ADC (5Msps) with hardware oversampling up to 16-bit, two 12-bit DAC channels, one operational amplifier with built-in PGA, and two ultra-low-power comparators. Communication interfaces include CAN 2.0B, three I2C FM+, four USARTs, three SPIs (one Quad SPI), and USB 2.0 FS. Housed in the industry-standard LQFP-64 (10x10mm) package with 52 I/O pins, the STM32L431RCT6 operates from 1.71V to 3.6V. It is ideal for IoT devices, wearables, medical instruments, industrial control, smart home automation, and remote environmental monitoring applications requiring ultra-low power consumption and reliable performance.
