You will need to get with the marketing group or the quality group. Based on previous experience, I can tell from the last 3 characters that the 3 lots were manufactured during 2016. The last character is for the sublot.</P><P></P><P>Regards,</P><P>John</P></BODY></HTML> Thu, 02 Feb 2017 21:22:23 GMT https://community.nxp.com/t5/8-bit-Microcontrollers/MC9S08QE128-Marking-Codes/m-p/657322#M22345 john_suchyta 2017-02-02T21:22:23Z
