Hello Kevin,

M20AGV is the way that Freescale has coded the "K20DX128VLF5" part number for devices that are too little to write the whole part number.

1N86B is the silicon mask revision. Each device has several revisions, with the known erratas related to each revision.

CTEXGBE is the data code, it gives information of when and where has been manufactured the chip.

Regards,

Santiago
