Markings on KL25 series 48-pin ICs

This is a bit of a lame question, but I am trying to move from the frdm KL25Z board to a custom board that uses the 48-pin variant (specifically the KL25z128VFT4 ) and I am having some trouble in getting things up and running. From looking closely, I noticed that the marking on the chips I have (which came from Digikey) actually say M25M7V whereas the MKL25Z128VKLF4 markings appear on the frdm board's IC. I suspect this may come down to size limitations on the IC, and so perhaps it has been compressed, but from searching around and checking the documentation, I cannot see where this is explained, and so I want to make sure I'm using the correct ICs!


Could anyone out there check their KL25z128VFT4 (or similar 48 pin ICs) and verify they markings? I have similar markings on the KL26 ICs that I got from digikey (M26M7VFT) so I suspect this is as it should be, but I figure I should check.


Thank you,
