ATF1504AS-10AI100

Overview

The ATF1504AS-10AI100 is a high-performance, electrically-erasable CPLD from the ATF1504AS series. It features 64 macrocells with up to 40 product terms per macrocell via expandable logic chains. The device operates at a maximum pin-to-pin delay of 10 ns and supports registered operation up to 125 MHz. It utilizes EEPROM technology for reprogramming and includes In-System Programmability (ISP) via JTAG. The component is housed in a 100-lead PQFP package and supports both 3.3V and 5.0V I/O configurations.

Feature Summary

• 64 Macrocells with flexible logic structure supporting up to 40 product terms per macrocell
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Enhanced routing resources with global bus and regional foldback bus architecture
• Advanced power management including automatic standby and pin-controlled power-down modes

Applications

• Complex logic integration replacing TTL, SSI, MSI, LSI, and classic PLDs
• PCI-compliant interface designs requiring high current drivers
• Systems requiring field-upgradable logic through ISP capabilities
• Applications needing reduced-power operation with programmable pin-keeper circuits

Procurement Notes

Verify the specific ordering suffix 'AI100' against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with 3.3V or 5.0V supply requirements as specified in the design. Confirm that the JTAG interface is enabled if ISP functionality is required, as disabling it may free additional I/O pins.

Selection Notes

Select this model for designs requiring 64 macrocells and high-speed performance with a 10 ns delay. Consider the 100-lead PQFP package constraints for PCB layout. Evaluate power consumption needs, as the standard mode draws higher current than the 'L' version. Ensure the design compiler supports the enhanced routing features for optimal resource utilization.

Part Context

The ATF1504AS belongs to the ATF1504AS/L family of Complex Programmable Logic Devices. It shares architectural similarities with other variants in the series but differs in speed grade and package options. The 'AS' designation indicates standard performance characteristics, while the '10' denotes the 10 ns speed grade. This part is part of Atmel's (now Microchip) proven electrically-erasable memory technology line.

Replacement Considerations

Direct replacements within the same family include ATF1504AS-7, ATF1504AS-15, ATF1504AS-20, and ATF1504AS-25, which offer different speed grades. Variants with 'L' suffixes provide lower power consumption. Cross-family replacements may require significant redesign due to differences in macrocell count and I/O configurations.
