@tedyapo For other "classic" semiconductor vendors, I've been told these are probably "gapfiller" runs done when one of the older fabs/lines isn't busy producing high-margin long-term (milgrad?) parts, and the "run the dirt out parts" you get when reopening a line after maintenance, where you don't produce large-area die due to low yield, and for the small parts, the characterization costs are too high for it to make commercial sense to qualify them to the same degree as the higher-spec parts.
