Functional Description

The Cypress PLDC20RA10 is a high-performance, sec-

ond-generation programmable logic device employing a flexi-

ble macrocell structure that allows any individual output to be

configured independently as a combinatorial output or as a

fully asynchronous D-type registered output.

The Cypress PLDC20RA10 provides lower-power operation

with superior speed performance than functionally equivalent

bipolar devices through the use of high-performance 0.8-mi-

cron CMOS manufacturing technology.

The PLDC20RA10 is packaged in a 24 pin 300-mil molded

DIP, a 300-mil windowed cerDIP, and a 28-lead square lead-

less chip carrier, providing up to 20 inputs and 10 outputs.

When the windowed device is exposed to UV light, the 20RA10

is erased and can then be reprogrammed.
