Functional Description

The Cypress PLDC20RA10 is a high-performance, second-generation programmable logic device employing a flexible 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-micron CMOS manufacturing technology.
