Functional Description
The Cypress PALCE20V8 is a CMOS Flash Erasable sec-
ond-generation programmable array logic device. It is imple-
mented with the familiar sum-of-product (AND-OR) logic struc-
ture and the programmable macrocell.
The PALCE20V8 is executed in a 24-pin 300-mil molded DIP,
a 300-mil cerdip, a 28-lead square ceramic leadless chip car-
rier, a 28-lead square plastic leaded chip carrier, and a 24-lead
quarter size outline. The device provides up to 20 inputs and
8 outputs. The PALCE20V8 can be electrically erased and re-
programmed. The programmable macrocell enables the de-
vice to function as a superset to the familiar 24-pin PLDs such
as 20L8, 20R8, 20R6, 20R4.
