Is the S32K312 a drop-in replacement for the S32K311 (both in 100-pin package)?

And if it isn't, what would the difference be?

Hi @klv222,

Yes, the pinout is identical.

Refer to the excel files attached to the reference manual.

Hello,
Yes, the S32K312 and S32K311 in the 100-pin package have the same pinout, so they are physically drop-in compatible from a PCB perspective. However, they are not a complete software drop-in replacement because there are differences in memory size and device features. Make sure the linker file, startup code, clock configuration, and peripheral usage match the target MCU before migrating. Always verify the exact part numbers and datasheet details for your application.

Best Regards
