Field Programmable Gate Array Procurement Notes

Verify the specific suffix '1PQ144C' against official Microsemi documentation to confirm package type and temperature grade. Check current lifecycle status as ACT2 series components may be End-of-Life or available via life-buy programs. Ensure compatibility with existing PCB footprints for 144-pin PQFP packages before procurement.

Field Programmable Gate Array Selection Notes

Select this model when design requirements exceed standard PLD capacities but do not necessitate larger FPGA families. Consider the 75 MHz speed grade relative to timing constraints. Verify that the 5V supply requirement aligns with system power rails, as lower voltage variants exist within the same family.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT2 family, a well-established line of FPGAs known for replacing multiple discrete TTL and PAL logic chips. The ACT2 architecture utilizes antifuse technology, offering permanent configuration once programmed. This specific part number represents a variant optimized for general-purpose logic integration in commercial environments.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements are limited due to the niche nature of the ACT2 family. Potential alternatives include other Microsemi ACT series parts with similar gate counts, though package and speed differences must be evaluated. Cross-referencing with generic CPLDs may require significant schematic redesign.
