Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'L' indicates the extended temperature range variant when sourcing. Confirm package integrity for the 44-pin PLCC form factor. Check for RoHS compliance status as per current manufacturing data sheets. Ensure programming tools are compatible with the ATF1504ASV/L architecture.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring moderate logic density with non-volatile EEPROM storage. Compare against the standard ATF1504AS if industrial temperature ratings are not required. Ensure the 44-pin PLCC footprint matches the PCB layout constraints. Verify power supply stability within the 3.0 V to 3.6 V window for reliable operation.

Complex Programmable Logic Devices Part Context

This part belongs to the ATF1504ASV/L family, which provides high-density programmable logic in compact packages. The 'L' suffix typically denotes an extended temperature grade compared to commercial variants. It serves as a drop-in replacement for older GALs and PALs in legacy designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible substitutes include other ATF1504ASV variants with matching speed grades. Verify that alternative CPLDs offer equivalent macrocell counts and I/O configurations. Check for software compatibility with existing programming files.
