ATF1504AS-7JC84

Overview

The ATF1504AS-7JC84 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 64 macrocells with five product terms each, expandable to 40 via cascade logic. The device supports In-System Programmability (ISP) via JTAG and offers a maximum pin-to-pin delay of 7.5 ns, enabling registered operation up to 125 MHz. It utilizes EEPROM technology for non-volatile configuration, providing 10,000 program/erase cycles and 20-year data retention. The component operates at 3.3V or 5.0V I/O levels and includes advanced power management features such as standby modes and programmable pin-keepers.

Feature Summary

• 64 Macrocells with 5 Product Terms per Macrocell, expandable to 40
• Maximum Pin-to-Pin Delay of 7.5 ns with Registered Operation up to 125 MHz
• In-System Programmability (ISP) via IEEE Std. 1149.1 JTAG Interface
• EEPROM Non-Volatile Memory with 10,000 Program/Erase Cycles

Applications

• High-density logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• PCI-compliant interface designs requiring high current drivers
• Complex state machine initialization and control applications
• Digital design applications requiring field modifications via software

Procurement Notes

Verify the specific ordering suffix JC84 against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for the 84-lead PLCC package if applicable. Confirm that the design compiler supports the required macrocell configurations and ISP protocols.

Selection Notes

Select this model for applications requiring high-speed logic with a 7.5 ns delay and 64 macrocells. Consider the ATF1504ASL variant if automatic microamp standby mode is required for low-power applications. Verify that the system voltage supports both 3.3V and 5.0V I/O options. Ensure the design toolchain supports JTAG boundary-scan testing and ISP programming.
