Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Check for specific revision markings on the die to ensure compatibility with existing design files.

Field Programmable Gate Array Selection Notes

Compare CLB count and I/O availability against current project requirements. Evaluate thermal performance within the PQFP-100 package constraints. Consider pinout compatibility if replacing older ACT series devices in existing footprints.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 family, designed as a single-chip ASIC alternative. It offers deterministic timing and high resource utilization capabilities typical of early-generation FPGAs, serving as a bridge between fixed logic and more complex programmable solutions.

Field Programmable Gate Array Replacement Considerations

No direct public substitute part numbers are confirmed for this specific variant. Designers should evaluate modern FPGA families from Microchip or other vendors for functional equivalence, noting significant architectural differences.
