Marking description (continued)
For topside marking, “7” is the family number, followed by the V
threshold and device number (1,9 = STM6717, 2 = 6718, 3 = 6719, 4 = 6720, 5 = 6777,
6 = 6778, 7 = 6779, 8 = 6780).
For bottomside marking, “P” = assembly site, “Y” = 1-digit year, and “WW” = 2-digit work
week.
