Field Programmable Gate Array Procurement Notes

This component is officially listed as obsolete by the manufacturer. Procurement is restricted to surplus or secondary market channels. Buyers must verify the authenticity of the source and check for potential moisture sensitivity damage due to age. Standard packaging quantities may vary among distributors, and lead times are not guaranteed. Engineering change notices should be reviewed prior to acquisition.

Field Programmable Gate Array Selection Notes

Select this part only when specific legacy compatibility with the ACT™ 1 family is required. Verify that the 80-VQFP footprint matches the target PCB design. Ensure the 0°C to 70°C operating range meets environmental requirements. Consider modern alternatives if new production is planned, as end-of-life status limits long-term availability.

Field Programmable Gate Array Part Context

The A1020B-VQG80C is part of the Microsemi ACT™ 1 series, which represents an early generation of embedded FPGAs. This series was designed to replace complex discrete logic and simple PLDs. The 'A1020' designation indicates a specific gate count tier within the family, offering a balance of logic density and pin count for mid-range applications during its active production period.

Field Programmable Gate Array Replacement Considerations

Publicly confirmed substitute part numbers are not available for this obsolete component. Engineers typically migrate to newer Microsemi SmartFusion or IGLOO families, or equivalent devices from other vendors, though these require significant schematic and firmware redesign.
