ATF1504ASL-25AU100

Overview

The ATF1504ASL-25AU100 is a high-performance, electrically-erasable Complex Programmable Logic Device (CPLD) from Microchip Technology. It features 64 macrocells with up to 68 inputs and operates on a 5V supply voltage. The device provides 100 I/O pins in a TQFP-100 package. Key electrical parameters include a maximum propagation delay of 25 ns, a maximum operating frequency of 60 MHz, and an industrial temperature range of -40°C to +85°C. It utilizes EEPROM storage technology for reprogramming.

Feature Summary

• In-System Programmability (ISP) via JTAG interface
• Flexible logic macrocell with D/T/Latch configurable flip-flops
• Advanced power management with pin-controlled standby mode
• Programmable pin-keeper circuits to prevent floating inputs

Applications

• Logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• PCI-compliant system designs
• Boundary-scan testing applications

Procurement Notes

Verify the specific suffix 'AU100' corresponds to the TQFP-100 package and industrial temperature grade (-40°C to +85°C). Confirm that the 'L' variant meets the required power consumption specifications, as it includes automatic standby features distinct from the standard AS version. Ensure design files account for the 5V I/O requirements.

Selection Notes

Select this component when 64 macrocells and 100 I/O pins are required within a TQFP-100 footprint. The 25 ns speed grade supports frequencies up to 60 MHz. Consider the ATF1504ASL variant if low-power standby modes are necessary, as it offers reduced current consumption compared to the non-L version. Verify compatibility with 5V logic levels.

Part Context

This part belongs to the ATF1504AS(L) series, which includes variants with different speed grades (-7, -10, -25) and packages (44, 84, 100 pins). The ATF1504ASL specifically denotes the low-power version of the ATF1504AS CPLD family, sharing the same logical architecture but optimized for power efficiency.

Replacement Considerations

Direct replacements within the same family include other ATF1504ASL variants with different speed grades or packages, such as ATF1504ASL-25AU44 (TQFP-44) or ATF1504ASL-25AC84 (PLCC-84), provided pin counts and thermal requirements match.
