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 leadless
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.
