ATF1504ASVL-20AI100

Complex Programmable Logic Devices Overview

The ATF1504ASVL-20AI100 is a high-density, electrically-erasable CPLD from Microchip Technology. It features 64 macrocells with up to 40 product terms each and operates within a 3.0V to 3.6V supply range. The device supports In-System Programmability (ISP) via JTAG and offers automatic low-power standby mode. Key electrical specifications include a maximum pin-to-pin propagation delay of 20 ns, a maximum internal clock frequency of 66 MHz, and an operating temperature range of -40°C to +85°C. It utilizes EEPROM technology for reprogramming.

Complex Programmable Logic Devices Feature Summary

• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Automatic low-power Standby mode (typical 5 µA) for the ASVL variant
• Industrial temperature range (-40°C to +85°C) and robust EEPROM endurance

Complex Programmable Logic Devices Applications

• Complex logic integration replacing TTL/SSI/MSI/LSI components
• JTAG boundary-scan testing and in-system programming
• PCI-compliant logic design applications
• State machine initialization with power-up reset features

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'AI100' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with 3.3V I/O levels and check for any discontinued status or lifecycle notices associated with this specific part number before procurement.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring 64 macrocells with ISP capabilities. The ASVL variant is suitable for low-power applications due to its automatic standby mode. Ensure the design accommodates the 3.0V-3.6V supply voltage and verify that the 100-lead TQFP package fits the PCB layout constraints.

Complex Programmable Logic Devices Part Context

This part belongs to the ATF1504ASV/L family of Complex Programmable Logic Devices. It shares architectural similarities with other members like ATF1504ASV-15AU100 but differs in speed grade (20 ns vs 15 ns) and power management features (ASVL includes automatic standby).

Complex Programmable Logic Devices Replacement Considerations

Direct replacements must match the 64 macrocell count, 100-lead TQFP package, and 3.3V operation. Verify if alternative speed grades (e.g., -15) are functionally compatible. Check for end-of-life notices on similar Microchip CPLDs.
