ATF1504AS-10QC100

Overview

The ATF1504AS-10QC100 is a high-performance, electrically-erasable complex programmable logic device (CPLD) from the ATF1504AS family. It features 64 macrocells with up to 40 product terms per macrocell via cascade expansion and supports registered operation up to 125 MHz. The device operates at 5V or 3.3V I/O levels and offers a maximum pin-to-pin delay of 10 ns. Packaged in a 100-lead PQFP, it includes In-System Programmability (ISP) via JTAG, enhanced routing resources, and advanced power management features such as standby modes.

Feature Summary

• 64 Macrocells with flexible D/T/Latch flip-flops and up to 40 expandable product terms
• In-System Programmability (ISP) using standard 4-pin JTAG interface
• Maximum propagation delay of 10 ns with registered operation up to 125 MHz
• Supports 5.0V and 3.3V I/O standards with programmable slew rates

Applications

• PCI-compliant interface designs requiring high current drivers
• Complex logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• Systems requiring field design modifications via software updates

Procurement Notes

Verify the package type matches the 'QC' suffix for 100-lead PQFP. Confirm the speed grade corresponds to the '-10' designation for 10 ns delay. Ensure the voltage rating aligns with system requirements for 5V or 3.3V operation. Check for RoHS compliance status if required by specific manufacturing standards.

Selection Notes

Select this model when 64 macrocells are sufficient for the logic density. Choose the -10 speed grade for applications requiring 10 ns delays. Use the QC100 variant for surface-mount assembly in 100-lead PQFP packages. Consider the ASL version if automatic microamp standby mode is needed for lower power consumption.

Part Context

This component belongs to the ATF1504AS series of high-density CPLDs. It utilizes Atmel's electrically-erasable memory technology, allowing for complete reprogrammability and 10,000 program/erase cycles. The series supports various pin counts including 44, 68, 84, and 100 pins across different package types like PLCC, TQFP, and PQFP.

Replacement Considerations

ATF1504ASL-20QC100: Similar 100-lead PQFP package but with 20 ns delay and low-power standby features.
