Ultra low power, Vcc-1.8V, 32 MC, ISP , High Speed CPLD in Fully Green Package
The ATF1502BE is a high-performance, high-density complex programmable logic device
(CPLD) that utilizes Atmel’s proven electrically-erasable technology. With 32 logic macrocells
and up to 36 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs.
The ATF1502BE’s enhanced routing switch matrices increase usable gate count and the odds
of successful pin-locked design modifications.
The ATF1502BE has up to 32 bi-directional I/O pins and four dedicated input pins, depending on
the type of device package selected. Each dedicated pin can also serve as a global control signal,
register clock, register reset or output enable. Each of these control signals can be selected
for use individually within each macrocell. Figure 1-1 shows the pin assignments for 44-lead
TQFP Package.

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.
