STM32F031 in STM32 Family
The STM32F031 sub-family is a series of entry-level 32-bit microcontrollers produced by STMicroelectronics, built on the ARM Cortex-M0 core. Operating at frequencies up to 48 MHz, these MCUs bridge the gap between legacy 8-bit or 16-bit systems and more complex 32-bit architectures. They provide a cost-effective solution for real-time control and general-purpose processing where a small footprint and low power consumption are prioritized over high-end computational performance.

| Part Number | I/O Pins | Package | Stock |
|---|---|---|---|
| STM32F031C6T6 (STMicroelectronics) | 39 | LQFP-48 | 1,117 |
| STM32F031K6T6 (STMicroelectronics) | 25 | LQFP-32 | 2,785 |
Variants within the STM32F031 sub-family primarily differ based on their Flash memory density and package pin counts. Flash capacities range from 16 KB to 32 KB, while SRAM remains consistent at 4 KB across the family. Packaging options span from 20-pin TSSOP for minimal I/O requirements up to 48-pin LQFP or UFQFPN layouts to accommodate more complex peripheral multiplexing and GPIO-intensive designs.
