 |
|
I'm designing new version of Intel Advanced SDK-85 , I need to add Intel's D27C400 to my PCB but I don't know how to connect pin no (29 = O15 / -A1) in my schematic diagram.
Any advice.

| Pin O15/A-1 is least significant address bit input in Byte-Wide Mode. I assume that you want use 27C400 in Byte-Wide Mode. So you connect CPU A0 to EPROM A-1, A1 to A0 and so on. |
