ATF1504AS-15AI100

Overview

The ATF1504AS-15AI100 is a high-performance, high-density Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell and supports 100 pins in a PQFP package. The device operates at a maximum pin-to-pin delay of 15 ns and a registered frequency of up to 76.9 MHz. It utilizes electrically-erasable memory technology, offering In-System Programmability (ISP) via JTAG, 10,000 program/erase cycles, and 20-year data retention. The component supports both 3.3V and 5.0V I/O configurations.

Feature Summary

• 64 Macrocells with flexible logic structure supporting D/T/Latch configurable flip-flops
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Enhanced routing resources with global bus and regional foldback bus
• Advanced power management including pin-controlled standby mode

Applications

• Logic integration for TTL, SSI, MSI, LSI, and classic PLDs
• PCI-compliant interface designs requiring high current drivers
• Boundary-scan testing and system-level diagnostics
• State machine initialization with power-up reset features

Procurement Notes

Verify the specific ordering suffix 'AI' against official Microchip documentation to confirm temperature range and package details, as datasheet tables list commercial and industrial variants. Confirm availability status directly with the manufacturer or authorized distributors, as lead times and stock levels are subject to change.

Selection Notes

Select this component for applications requiring high-density logic in a 100-pin surface-mount package. Ensure design compatibility with either 3.3V or 5.0V supply voltages, as the device supports both. Consider the 15 ns speed grade if timing constraints require delays between 10 ns and 15 ns. Verify that the design compiler supports the required macrocell configuration and ISP programming requirements.

Part Context

This part belongs to the ATF1504AS/L series of CPLDs from Microchip Technology. The series is characterized by its electrically-erasable memory technology and support for various package types including PLCC, TQFP, and PQFP. The ATF1504AS variant specifically targets high-performance applications with enhanced routing capabilities compared to earlier generations.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified replacements. Potential alternatives within the same family include other ATF1504AS speed grades or pin-compatible packages such as the ATF1504ASL series. Ensure any substitute maintains the 64 macrocell count and 100-pin form factor.
