Parallel Programming Interface
The EPROM interface is a 17-wire connection. Review the part-speciï¬c pin dia-
grams in Figures 2 through 5 for part pin-out.
Pin Diagrams
Device pin-out diagrams for the 18-pin DIP/SOIC and 20-pin SSOP are shown in
Figures 2 through 5. There are two conï¬gurations for the 20-pin SSOP deviceâ
the corresponding parts are identiï¬ed in the diagrams.
