ATF1504AS-15AC100

Overview

The ATF1504AS-15AC100 is a high-performance, electrically-erasable CPLD from Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell and supports 100 I/O pins in a PQFP-100 package. The device operates at a maximum frequency of 83.3 MHz with a typical propagation delay of 15 ns. It utilizes EEPROM technology for reprogramming, offers In-System Programmability (ISP) via JTAG, and supports both 3.3V and 5.0V I/O levels within the commercial temperature range.

Feature Summary

• 64 Macrocells with enhanced routing resources and up to 40 expandable product terms
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Supports 3.3V or 5.0V I/O pins with programmable slew rates
• Advanced power management including pin-controlled standby and reduced-power modes

Applications

• High-density logic integration replacing TTL/SSI/MSI components
• PCI-compliant interface designs requiring high current drivers
• Complex state machine implementations with registered feedback
• Boundary-scan testing and system-level diagnostics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type, speed grade, and voltage compatibility. Ensure design files account for the correct pinout and electrical characteristics associated with the AC100 designation before procurement.

Selection Notes

Select this component for applications requiring 64 macrocells and 100 I/O pins. Confirm that the system voltage aligns with the 3.3V or 5.0V I/O requirements. Consider the 15 ns delay and 83.3 MHz frequency limits for timing closure. Verify if ISP capabilities are required for field updates.

Part Context

This part belongs to the ATF1504AS/L series of Complex Programmable Logic Devices. It shares architectural similarities with other members of the family but differs in package configuration and speed grading. The 'AS' variant typically denotes standard performance characteristics within the electrically erasable PLD category.

Replacement Considerations

Direct replacements must match the 64 macrocell count, 100-pin PQFP package, and 15 ns speed grade. Verify pin compatibility and electrical specifications with alternative CPLDs from the same manufacturer or compatible families.
