Hi Jonas,
For MAX 10 SA to SC migration, please do not assume full pin compatibility only because the package is the same. Some pins can have different functions between feature options, for example analog pins on SA may become power or GND pins on SC.
The recommended approach is to compare the official MAX 10 pin-out file for both exact ordering part numbers and check the MAX 10 Pin Connection Guidelines for unused or dual-purpose pin handling. Altera provides MAX 10 pinout files and pin connection guidelines for this purpose.
In general:
- Pins defined as GND or power pins for one device option must follow that device requirement.
- Unused dual-purpose or analog-related pins should follow the pin connection guideline.
- If one PCB must support both SA and SC variants, it is safer to provide board-level options such as jumper or stuffing option for pins that are different.
Regards,
