ATF1504ASV-15JC44

Overview

The ATF1504ASV-15JC44 is a high-performance, electrically-erasable CPLD from Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell and operates within a 3.0V to 3.6V supply range. The device supports In-System Programmability (ISP) via JTAG and offers a maximum pin-to-pin delay of 15 ns. It includes enhanced routing resources, flexible logic macrocells, and advanced power management features such as standby modes. The component is housed in a 44-lead PLCC package and is designed for industrial temperature ranges.

Feature Summary

• 64 Macrocells with 5 product terms each, expandable to 40 via cascade logic
• In-System Programmability (ISP) using standard 4-pin JTAG interface
• Maximum propagation delay of 15 ns with registered operation up to 77 MHz
• Robust EEPROM technology supporting 10,000 program/erase cycles and 20-year data retention

Applications

• Logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• PCI-compliant system design applications
• JTAG boundary-scan testing and debugging
• State machine initialization requiring power-up reset features

Procurement Notes

Verify the specific ordering suffix 'JC' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with 3.3V I/O levels and check for RoHS compliance status in current production notices. Confirm availability through authorized distributors as lead times may vary.

Selection Notes

Select this model for designs requiring 64 macrocells and ISP capability in a 44-pin surface-mount or PLCC package. Consider the ATF1504ASVL variant if automatic low-power standby mode is required. Ensure the design compiler supports the enhanced routing resources and flexible macrocell configuration options available in this series.

Part Context

This component belongs to the ATF15xx family of Complex Programmable Logic Devices. It utilizes Microchip's electrically-erasable memory technology, offering reprogrammability and security fuse protection. The device integrates global clock pins, output enable controls, and programmable pin-keeper circuits to optimize performance and power consumption in embedded logic applications.
