ATF1504AS-10QI100

Overview

The ATF1504AS-10QI100 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 pins in a PQFP package. The device operates at a maximum frequency of 100 MHz with a typical pin-to-pin delay of 10 ns. It utilizes EEPROM technology for reprogramming, supports In-System Programmability (ISP) via JTAG, and offers flexible I/O configurations for 3.3V or 5.0V systems.

Feature Summary

• 64 Macrocells with expandable logic capacity up to 40 product terms
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Maximum operating frequency of 100 MHz with 10 ns propagation delay
• Supports both 3.3V and 5.0V I/O voltage levels

Applications

• PCI-compliant interface designs
• Complex state machine implementations
• High-density logic integration replacing TTL/SSI/MSI components
• Field-upgradable logic circuits via ISP

Procurement Notes

Verify the specific suffix 'QI' against official documentation to confirm package type and temperature range. Confirm RoHS compliance status as specifications may vary by manufacturing batch. Ensure design files account for the 100-lead PQFP footprint dimensions.

Selection Notes

Select this model for applications requiring 64 macrocells and 100 I/O pins. The -10 speed grade provides a 10 ns delay suitable for frequencies up to 100 MHz. Consider the -L variant if ultra-low standby current is required, as the standard AS version has higher standby power consumption.

Part Context

This component belongs to the ATF1504AS/L family of Complex Programmable Logic Devices. It shares architectural similarities with other members like the ATF1504AS-10JC84 but differs in package configuration and pin count. The family is characterized by its EEPROM-based non-volatile memory and flexible macrocell structure.

Replacement Considerations

Direct replacements within the same family include ATF1504AS-10QU100 or ATF1504AS-10AU100-T, depending on the required package type (PQFP vs TQFP). Verify pin compatibility and electrical characteristics before substitution.
