MC9S12A to MC9S12XA

[Didier91]

Hello,

I have a question that you will certainly find ridiculous but nevermind.

Maybe it has even been asked, but my research did not give anything ...

I regularly use an MC9S12A256 microcontroller. my question is:

Is it possible to replace it with an MC9S12XA256 without modification or software or hardware?

thanks a lot for your help

Didier

Hi,

No, there are a lot of differences.
See https://www.nxp.com/docs/en/application-note/AN2615.pdf  to investigate them.

Best regards,

Ladislav
