Keywords: xc4025e, PG223, HQ240, PG299, HQ304, BG352, address
pins

Urgency: Standard

The 9/96 Databook pinout table representing the 4025E,
4028EX, and 4028XL shows 21 address lines.  However, the
4025E has only 17 address lines.


Solution 1:

Address pins A18, A19, A20, and A21 are for the 4028EX and 4028XL.
For the 4025E disregard adresses on the table greater than A17.
