Reference Design
 Atmel CPLD Reference Designs  This document describes three full applications using Logic Doubling techniques:
  1. 8255 Serial IO expander with IO enable on every pin
  2. Low Power Serial IO expander and 32 LED driver
  3. Four 8-bit PWM generators, bus interface and value latches
Each fits in a 32 macrocell ATF1502 device. It also describes how to add transparent pin latch, ala HC573/373 into a corner of your CPLD. Click here for the Reference Design files for all these designs, plus a fourth Low Power Serial IO expander and 32 LCD driver application that uses each macrocell three ways and a Logic Doubling Tutorial.
