Is there a pin-compatible replacement for STM32F030C8T6?

GigaDevice's GD32 series is often marketed as pin-compatible, but candidates like GD32F330C8T6 have different electrical characteristics and use a more advanced Cortex-M4 core, requiring careful review. A true pin-compatible replacement is not guaranteed without datasheet comparison.

What risks should I check before replacing STM32F030C8T6?

Key risks include pinout differences, voltage supply range mismatches, peripheral variations (ADC, timers, communication), and firmware toolchain compatibility. Always verify the candidate's datasheet against your design's specific requirements.
