The ATF1508AS is a high-performance, high-density complex programmable logic device (CPLD) that utilizes Atmel’s proven electrically-erasable technology. With 128 logic macrocells and up to 100 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1508AS’s enhanced routing switch matrices increase usable gate count and increase odds of successful pin-locked design modifications. The ATF1508AS has up to 96 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. Each of the 128 macrocells generates a buried feedback that goes to the global bus. Each input and I/O pin also feeds into the global bus. The switch matrix in each logic block then selects 40 individual signals from the global bus. Each macrocell also generates a foldback logic term that goes to a regional bus. Cascade logic between macrocells in the ATF1508AS allows fast, efficient generation of complex logic functions. The ATF1508AS contains eight such logic chains, each capable of creating sum term logic with a fan-in of up to 40 product terms. The ATF1508AS macrocell, shown in Figure 1, is flexible enough to support highly-complex logic functions operating at high speed. The macrocell consists of five sections: product terms and product term select multiplexer; OR/XOR/CASCADE logic, a flip-flop, output select and enable, and logic array inputs. Unused macrocells are automatically disabled by the compiler to decrease power consumption. A security fuse, when programmed, protects the contents of the ATF1508AS. Two bytes (16 bits) of User Signature are accessible to the user for purposes such as storing project name, part number, revision or date. The User Signature is accessible regardless of the state of the security fuse. The ATF1508AS device is an in-system programmable (ISP) device. It uses the industry-standard 4-pin JTAG interface (IEEE Std. 1149.1), and is fully compliant with JTAG’s Boundaryscan Description Language (BSDL). ISP allows the device to be programmed without removing it from the printed circuit board. In addition to simplifying the manufacturing flow, ISP also allows design modifications to be made in the field via software.

    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.
