MK22FX512VLL12 / MK22FX512AVLL12 binary compatibility

pmdwyer — Mon, 07 Aug 2023 14:25:59 GMT

We are using the MK22FX512VLL12 in one of our boards and saw that it is not recommended for new designs. Would it be possible to use the MK22FX512AVLL12 as a replacement without having to recompile the firmware? I've been comparing the datasheets for both and it seems possible, but we would like to confirm our suspicions. Also, is there any official list of changes between the two?

Thanks,

Patrick

Hello, my name is Pavel, and I will be supporting your case, I suggest reviewing the errata maybe in that document you can find some differences.

I´m afraid NXP does not warrant the same behavior with only one binary, the MCU seems similar, but the recommendation is to compile the project.

Best regards,
Pavel
