Product details

Memory and peripheral budget

With 16 KB of program Flash and 4 KB of SRAM, the firmware footprint needs to stay lean — think bootloader plus a single application layer, not a full RTOS with graphics stack. The 15 available I/O pins (in the 20-TSSOP) cover a handful of sensor inputs, a serial link, and a few PWM outputs. The 12-bit ADC with 12 multiplexed channels handles analog sensing without an external converter.

Active lifecycle — no near-term obsolescence

ROHS3 compliance is confirmed, so it passes EU and similar regulatory requirements.

Frequently asked questions

Is STM32F031F4P6TR obsolete or discontinued?

There is no announced end-of-life or last-time-buy window.

Is there a pin-compatible replacement or equivalent for STM32F031F4P6TR?

The STM32L151CBU6A is a different series (STM32L1) with a Cortex-M3 core, 32 MHz speed, and a 37-I/O package — it is not a pin-compatible or footprint-equivalent drop-in. For a direct second source within the STM32F0 family, consider other 20-pin TSSOP variants in the STM32F031 series with matching Flash and SRAM densities.
