Overview
The STM32L031C6U6 is a member of the ultra-low-power STM32L031x4/6 family of microcontrollers from STMicroelectronics. This device is built around the high-performance ARM® Cortex®-M0+ 32-bit RISC core, operating at a frequency of up to 32 MHz. It features high-speed embedded memories, including up to 32 Kbytes of Flash program memory, 1 Kbyte of data EEPROM, and 8 Kbytes of RAM. The STM32L031C6U6 is designed to provide high power efficiency, achieved through a large choice of internal and external clock sources, internal voltage adaptation, and several low-power modes. This makes it an ideal choice for battery-powered devices that require extended operation times.
