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.
