ATF1504ASV-15AU100

Overview

The ATF1504ASV-15AU100 is a high-performance, electrically-erasable CPLD from Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell and supports a 3.0V to 3.6V operating range. The device offers a maximum pin-to-pin delay of 15 ns and registered operation up to 76.9 MHz. It includes In-System Programmability (ISP) via JTAG, enhanced routing resources, and flexible logic macrocells with configurable flip-flops. Packaged in a 100-Lead TQFP, it provides 64 bidirectional I/O pins and four dedicated input pins for global control signals.

Feature Summary

• 64 Macrocells with 5 product terms each, expandable to 40 via cascade logic
• In-System Programmability (ISP) using standard 4-pin JTAG interface
• Maximum propagation delay of 15 ns with registered operation up to 76.9 MHz
• Flexible Logic Macrocell supporting D/T/Latch flip-flops and programmable output slew rates

Applications

• Complex logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• High-speed digital signal processing requiring fast registered inputs
• Systems requiring robust EEPROM technology with 10,000 program/erase cycles
• PCI-compliant designs utilizing boundary-scan testing capabilities

Procurement Notes

Verify the specific suffix 'AU100' corresponds to the 100-Lead TQFP package and industrial temperature range (-40°C to +85°C). Confirm that the design software supports the ATF1504ASV series for proper fitting and programming. Ensure the ISP interface utilizes the correct JTAG pins as defined in the datasheet pinout tables.

Selection Notes

Select this model when a 3.3V supply voltage is required with high-density logic capabilities. The 100-lead package is suitable for designs needing 64 user I/Os. Consider the ATF1504ASVL variant if automatic low-power standby modes are necessary, as the ASV version requires manual power-down control via PD pins.

Part Context

This component belongs to the ATF15xx family of Complex Programmable Logic Devices. It utilizes Microchip's proven electrically-erasable memory technology. The ASV designation indicates the 3.3V operating voltage variant, distinguishing it from the 5V ASL series. The AU100 suffix specifies the 100-lead Thin Quad Flat Package (TQFP) form factor.

Replacement Considerations

The ATF1504ASL-15AU100 serves as a direct functional replacement if a 5V operating voltage is acceptable instead of 3.3V. Other ATF1504 variants with different package sizes or speed grades may require schematic and layout modifications.
