| | Atmel CPLD Reference Designs (White Paper, 17 pages, updated 1/01) 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. |
