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.

• QSOP package available

• High reliability
