as title, I want to upgrade my current ST7lite25 to a more powerfull MCU with faster speed and has more perepherals like GPIO RTC etc, but I'm a little bit worried about the source code porting,my understanding is if the MCU cores are different, there must be a big change in terms of source code porting, that means I have to take big risk for the MCU upgrading, anybody can give me any advice? thanks in advance.

if your code was written in assembler, you are up for a complete rewrite.

If it was written in C, most of it is reusable, especially if you switch to another micro but keep the same provider for the compiler.

Hope it helps.

thanks for your reply, the code are written in C language, we are considering reuse our current code, especially the parts of several peripherals like Timer/Counter,A/D,GPIO, any guy can suggest a more powerful MCU that has the same Timer,A/D,GPIO IPs as ST7Flite25?
