This white paper introduces a method for improving the I/O connectivity and logic reusability of Complex Programmable Logic Devices (CPLDs). This method, called Logic Doubling, works by splitting the logic circuit into two logic blocks and using different logic circuits in each logic block. This allows CPLDs to support more I/O ports and improve the reusability of logic circuits.

This document describes how to use the features of the ATV750 and ATV750B in the ABEL and CUPL high level description languages. The ATV750 and ATV750B are easy upgrades from a 22V10, offering twice the logic density and more flexibility in the same footprint. Both devices have 20 registers and individual clock and AR product terms for each register. Each I/O pin has a programmable polarity control and an individual output enable product term. Independent feedback paths from each register allow all of the registers to be buried without wasting the I/O pins. For the ATV750B, the registers can also be configured as D- or T-type and the clock can be selected as either a synchronous clock pin or a clock product term.
