ATF1508ASV-15AU100

Overview

The ATF1508ASV-15AU100 is a high-performance, electrically-erasable complex programmable logic device (CPLD) manufactured by Microchip Technology. It features 128 macrocells with up to 100 inputs and operates within a 3.0V to 3.6V supply range. The component provides a maximum pin-to-pin delay of 15 ns and supports registered operation frequencies up to 77 MHz. Packaged in a 100-lead TQFP format, it includes enhanced routing resources, flexible logic macrocells, and advanced power management features such as automatic standby modes. The device supports In-System Programmability (ISP) via JTAG and complies with PCI standards.

Feature Summary

• 128 Macrocells with 5 product terms each, expandable up to 40 per macrocell
• 15 ns maximum pin-to-pin delay and 100 MHz maximum operating frequency
• In-System Programmability (ISP) via 4-pin JTAG interface
• Advanced power management including 5 µA standby mode and pin-controlled power-down

Applications

• PCI-compliant system logic integration
• State machine initialization and control
• Replacement for TTL, SSI, MSI, LSI, and classic PLDs
• High-density logic design requiring field reprogrammability

Procurement Notes

Verify the specific ordering suffix 'AU100' against official Microchip documentation to confirm package type, temperature range, and environmental compliance details. Ensure compatibility with 3.0V to 3.6V VCC supply requirements and 100-lead TQFP footprint constraints during procurement planning.

Selection Notes

Select this component when designs require 128 macrocells with 15 ns speed performance in a 100-pin surface-mount package. Consider the ATF1508ASVL variant if automatic low-power standby modes are required. Verify that the 3.0V–3.6V operating voltage aligns with the target system's power rails before finalizing the selection.

Part Context

This part belongs to the ATF1508ASV family of Electrically Erasable Programmable Logic Devices (EEPLDs). It shares architectural similarities with other ATF1508 variants but differs in package configuration and electrical specifications. The ASV designation indicates the standard voltage range and performance tier within the broader CPLD portfolio.

Replacement Considerations

Direct replacements must match the 128 macrocell count, 15 ns delay, and 100-lead TQFP package. Verify voltage compatibility (3.0V–3.6V) and ISP/JTAG interface support. Cross-reference with other ATF1508 series parts like ATF1508AS-15QC100 only if voltage levels and package types are confirmed compatible.
