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.

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?
