DCT: The actual top-side marking has three additional characters that designate the year, month, and assembly/test site.

DCU: The actual top-side marking has one additional character that designates the assembly/test site.

YZP: The actual top-side marking has three preceding characters to denote year, month, and sequence code, and one following

character to designate the assembly/test site. Pin 1 identifier indicates solder-bump composition (1 = SnPb,

• = Pb-free).
