Hi,
is there a 64Kb drop-in replacement for the STM32C031G6U6 (which is only 32kb)?
We need to find a part where - ideally - we just use the same code without any mods, this is the most important part.
And is there perhaps a tool that helps with that? Or at least allows us to make an accurate comparison check between two parts?
We just use GPIOs and 1 x RS232 and 1 x I2C in their default pin locations.
Thank you

The STM32C031 is only available in 16 kB or 32 kB flash sizes.
The part selector in STM32CubeMX can help you narrow down and find a suitable chip. Here are STM32C0 chips with 64+ kB of flash.
Ultimately it depends on what your program does, but in most cases those will be able to run the same code without modification.
