ATF1508AS-10AU100

Overview

The ATF1508AS-10AU100 is a high-performance, high-density Electrically-Erasable Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 128 macrocells with up to 100 inputs and operates at a maximum pin-to-pin delay of 10 ns. The device supports registered operation up to 125 MHz and utilizes enhanced routing resources for flexible logic implementation. It offers 3.3V or 5.0V I/O compatibility, In-System Programmability (ISP) via JTAG, and advanced power management features including automatic standby and pin-controlled power-down modes.

Feature Summary

• 128 Macrocells with 5 product terms each, expandable to 40 via cascade logic
• 10 ns maximum pin-to-pin propagation delay
• In-System Programmability (ISP) using standard 4-pin JTAG interface
• Supports both 3.3V and 5.0V I/O supply voltages

Applications

• PCI-compliant interface designs
• Complex logic integration replacing TTL/SSI/MSI/LSI PLDs
• High-speed registered logic applications up to 125 MHz

Procurement Notes

Verify the specific suffix AU100 corresponds to the 100-lead TQFP package and commercial temperature range (-40°C to +85°C as per general family specs, though datasheet lists Commercial 0-70C and Industrial -40-85C; the 'A' usually denotes Industrial in Atmel/Microchip naming, but local source table lists -40 to +85 for similar AS parts. The provided table explicitly lists min temp -40 C and max +85 C for ATF1508AS-10AU100). Confirm RoHS compliance status if required for current manufacturing standards.

Selection Notes

Select this component when 128 macrocells are sufficient for the design logic density. Ensure the 100-lead TQFP package fits the PCB layout constraints. Verify that the system requires ISP capability via JTAG. Check if 3.3V or 5.0V I/O levels match the target system voltage requirements.

Part Context

This part belongs to the ATF1508AS series of EEPLDs from Microchip Technology (formerly Atmel). It is part of the high-performance CPLD family designed for complex logic applications requiring reprogrammability and high speed.

Replacement Considerations

Direct replacements within the same package and speed grade should be sought from the ATF1508AS series. Consider ATF1508AS variants with different speed grades (e.g., -7, -15) if timing margins allow, ensuring package compatibility.
