ATF1504ASVL-20JC44

Complex Programmable Logic Devices Overview

The ATF1504ASVL-20JC44 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 a maximum pin-to-pin propagation delay of 20 ns. It includes advanced power management features such as automatic standby mode and programmable pin-keepers. The component is housed in a 44-lead PLCC package and is rated for industrial temperature operation.

Complex Programmable Logic Devices Feature Summary

• 64 Macrocells with flexible logic structure and up to 40 expandable product terms per macrocell
• In-System Programmability (ISP) via standard 4-pin JTAG interface
• Automatic low-power Standby mode with typical 5 µA current consumption
• Programmable pin-keeper circuits to prevent floating inputs and reduce noise

Complex Programmable Logic Devices Applications

• Complex logic integration replacing TTL, SSI, MSI, or classic PLDs
• High-speed state machine implementations requiring registered operation
• Systems requiring robust EEPROM technology with 10,000 program/erase cycles
• PCI-compliant digital logic designs

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'JC44' against official Microchip documentation to confirm package type and temperature grade. The 'L' suffix indicates low-power characteristics. Confirm RoHS compliance status as manufacturing processes may update. Check for end-of-life notices as older CPLD families may be discontinued.

Complex Programmable Logic Devices Selection Notes

Select this model for applications requiring 3.3V operation with low static power consumption. Ensure the design utilizes the JTAG interface for programming if ISP functionality is required. Compare performance requirements against the -15 speed grade if higher frequency operation above 66 MHz is needed. Verify that the 44-pin PLCC footprint matches 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 the ATF1504ASV but differs in power specifications. The family utilizes Microchip's electrically-erasable memory technology, offering reprogrammability and security fuse features not found in volatile FPGA counterparts.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other ATF1504ASVL variants with different speed grades (e.g., -15) or packages (e.g., TQFP). Cross-family upgrades may require retiming analysis due to differences in routing resources and I/O capabilities.
