Hi Jeremy,
Some of the packages are marked as (from top to bottom):
M10AEV
1N86B
CTXX7AN
We know the second and third codes are the Mask Id, so as to take a look of the ERROR MASK List given by Nxp.
However, the first one "M10AEV" should tell us what kind of microcontroller we have.
Probably "M10" would mean that is a Kinetis K10 Series, but "AEV" should be related to the Part Id Number, mainly to know memory size.
Thanks in advance,
Diego
