ATF1504AS-10AC100

Overview

The ATF1504AS-10AC100 is a high-performance, electrically-erasable 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 10 ns and registered frequencies up to 125 MHz. It utilizes EEPROM technology for reprogramming, supports In-System Programmability (ISP) via JTAG, and offers flexible I/O configurations for both 3.3V and 5.0V systems.

Feature Summary

• 64 Macrocells with expandable logic capacity up to 40 product terms per macrocell
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Maximum propagation delay of 10 ns with registered operation up to 125 MHz
• Supports 3.3V or 5.0V I/O pins with programmable slew rates and open-collector options

Applications

• High-density logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• PCI-compliant interface designs requiring high current drivers
• Complex state machine implementations with power-up reset capabilities
• Systems requiring field modifications via software-based ISP

Procurement Notes

Verify the specific ordering suffix 'AC100' against official Microchip documentation to confirm package type and temperature range. Ensure design files include necessary flags for power-up reset hysteresis if large hysteresis is selected. Confirm JTAG boundary-scan support requirements for manufacturing test flows.

Selection Notes

Select this component for applications requiring high logic density in a 100-pin surface-mount package. Consider the 10 ns speed grade for systems operating below 125 MHz. Evaluate power management needs, as the standard 'AS' version lacks the automatic standby mode found in the 'ASL' variant. Verify voltage compatibility for 3.3V or 5V I/O levels.

Part Context

This part belongs to the ATF1504AS/L series of CPLDs, which are designed using Atmel's proven electrically-erasable memory technology. The series includes variants with different speed grades (-7, -10, -15, -20, -25) and packages (PLCC, TQFP, PQFP). The ATF1504AS specifically targets high-performance applications needing extensive routing resources and flexible macrocell configurations.
