ATF1504ASV-15JC68

Overview

The ATF1504ASV-15JC68 is a high-performance, electrically-erasable CPLD from Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell via expansion. The device operates within a 3.0V to 3.6V supply range and supports In-System Programmability (ISP) via JTAG. Key electrical specifications include a maximum pin-to-pin delay of 15 ns and registered operation up to 77 MHz. It includes advanced power management features such as automatic standby mode and programmable pin-keepers.

Feature Summary

• 64 Macrocells with flexible logic structure and up to 40 expandable product terms
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Maximum 15 ns pin-to-pin propagation delay with 77 MHz registered speed
• 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
• Boundary-scan testing and in-system programming

Procurement Notes

Verify the package type for the JC suffix against official documentation, as datasheet listings specify 44-Lead PLCC and TQFP options. Confirm industrial temperature range (-40°C to +85°C) and RoHS compliance status prior to ordering. Ensure design tools support the specific speed grade -15.

Selection Notes

Select this component for designs requiring 64 macrocells and 3.3V operation. The -15 speed grade offers 15 ns delay suitable for frequencies up to 77 MHz. Consider the ASVL variant if automatic low-power standby modes are required. Verify I/O count requirements against the 44-pin package limitations.

Part Context

This part belongs to the ATF1504ASV/L family of Complex Programmable Logic Devices. It utilizes Microchip's electrically-erasable memory technology. The family provides enhanced routing resources and flexible macrocells for high-density logic applications.

Replacement Considerations

Direct replacements within the same family include other speed grades like ATF1504ASV-20 or different package variants such as ATF1504ASV-15QC44. Cross-family upgrades may require retargeting to newer Microchip CPLD architectures.
