Description

Unable to find and identify information about Marking lines on an Intel® Ethernet Adapter chip

This information is printed on the chip itself and is used to identify general details about the item:

Line 1: Marketing Name (WG82574L)
Line 2: TSMC Fab Lot Number Xxxxxxxxx or Xxxxxxxx.x
Line 3: Assembly Date Code YYWW, 3-digit QDF Number (omit the Q), ES
Line 4: INTEL, © Copyright including two number date code, circled e3 lead-free mark
Line 5: Country of Origin

Note

A-0 is Q 017 so line #3 would read the Assembly Date Code YYWW then 017ES. A-1 is Q FHU so line #3 would read the Assembly Date Code YYWW then FHUES.

The above information can also be found in the Engineering Samples Marking Diagrams section in the Intel® 82574 Family Gigabit Ethernet Controller Specification Update.
