Hello, I was planning to use the MK22FN512VDC12 for a project, but it looks like now its unavailable from most distributors. It looks like there are variants which are in stock. In particular I'm thinking of dropping in the MK22FX512AVMC12 as a replacement.
MK22FN512VDC12 NXP USA Inc. | Integrated Circuits (ICs) | DigiKey
MK22FX512AVMC12 NXP USA Inc. | Integrated Circuits (ICs) | DigiKey
From a compatibility point of view, it looks like the MK22FN512VDC12 has an XFBGA package, and the other one is MAPBGA. From what I can tell, the only difference appears to be the height of the package.
Other than that, I'm trying to make sure the pin muxing is still the same. I know the AVMC device has FlexNVM, which would be a really upgrade.
Does anyone have any recommendation on what I should consider to make sure they are compatible? I'm making sure the MCG peripheral is the same, and that I can match all the pins with the Kinetis Config tools, but is there anything else that might be a red flag?
Perhaps as a side note, does anyone know why the VDC12 variant isn't in stock anywhere?
Thanks,
Stephen

Dear Stephen Cripps,
There are a couple of differences:
MK22FN512VDC12 <---512KB Flash, 128KB SRAM
MK22FX512AVMC12 <---512KB Flash + 128KB FlexMem, 128KB RAM
they have the same pitch of balls and the dimensions of the package are almost the same the MAPBGA is 1mm higher than the XFBGA. from pin to pin i noticed a couple differences: please check the next image.
but it is compatible pin to pin.
hope this was helpful.
have a great day !
Best regards.
Jonathan

This is excellent, thanks for putting this together!
So was your strategy to put the pin mapping diagrams side by side? I was thinking of copying the Pin function/alt mode selection table into excel, but it became unwieldy rather quickly.
Cheers,
Stephen
