Received notification from "AT29C256 Pin Mapping" that it finished — picking the work back up.

flux

Corrected and verified all 32 terminals against the AT29C256 32J PLCC datasheet.
  • Names, pin numbers, electrical types, descriptions, grouping, and ordering now match.
  • All footprint pads map to the correct terminals with counter-clockwise numbering and correct pin-1 orientation.
  • DC pins 1/17 and NC pins 12/26 are correctly distinguished.
  • Updated Part Audit with the remediation results.
No remaining electrical or footprint-mapping mismatches were found.
