Overview

The ATF1508ASV-15AU100 is a high-performance, 128-macrocell Complex Programmable Logic Device (CPLD) utilizing Microchip High-density EEPROM technology. Operating at a 3.3V supply voltage with a 15ns propagation delay, it provides a flexible logic architecture that supports In-System Programmability (ISP) via JTAG. This device is designed to replace multiple TTL or PLD components while offering advanced power management and pin-to-pin compatibility with industry-standard architectures.

Why Choose This Part

It features flexible macrocell routing with additional feedback paths, allowing complex logic functions to be implemented without exhausting macrocell resources. The device supports 10,000 program/erase cycles and provides 20-year data retention for high reliability in industrial environments. Integrated Input Transition Detection (ITD) circuits and automatic standby modes help manage power consumption in 3.3V systems.

Applications

Legacy TTL Integration
Consolidating multiple 74-series logic chips into a single CPLD to reduce PCB footprint and complexity.
System Glue Logic
Managing address decoding, handshake signals, and bus arbitration between microprocessors and peripherals.
I/O Expansion
Adding custom GPIO or protocol-specific interfaces to systems with limited native microcontroller pins.
PCI Bus Interfacing
Implementing PCI-compliant logic for industrial backplane communication and data routing.

Getting Started

Design entry is typically performed using HDL tools like WinCUPL or industry-standard synthesis tools that support Atmel/Microchip CPLD architectures. Programming is achieved through the JTAG interface (IEEE 1149.1) using an ISP-compatible hardware programmer such as the ATDH1150USB. Engineers should utilize the Pin-locked architecture to maintain PCB layout consistency during logic updates.
