The 10-channel 12-bit ADC handles analog inputs like thermistors or potentiometers without an external converter. ## Package and footprint — 32-LQFP, 26 I/O Housed in a 32-LQFP (7x7 mm) package with 26 general-purpose I/O pins, this MCU fits on compact PCBs and is hand-solderable for prototyping. The surface-mount LQFP footprint is standard across the STM32L0 series, so a board layout can be reused with higher-density Flash variants without a respin. ST lists the STM32L031K6T3 as Active. The base product number STM32L031 covers multiple Flash and package options, giving the BOM some density flexibility without requalification.","metaTitle":"STM32L031K6T3 STMicroelectronics ARM Cortex-M0+ MCU, 32 MHz","metaDescription":"STM32L031K6T3 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 32KB Flash, 8K x 8 SRAM, 1K x 8 EEPROM, -40°C to 125°C, 32-LQFP.

The main difference is Flash and RAM density — the STM32L031K6T3 sits at 32 KB Flash / 8K x 8 SRAM. Higher-density siblings in the same package (e.g., STM32L031K8T3 with 64 KB Flash) are pin-compatible drop-in upgrades if firmware grows.
