Now I bought a lot with DC 2049, but it’s Die marking Z1409, Copyright 2007, Datecode marking: J CBBAA2049A. i.e. Die revision identifier & fab process code is "ABG" for DC 2131, 2149 and 2207; but "BAA" for DC 2049. So I question is the Datecode marking: J CBBAA2049A correct. Please advise, thanks.
