Field Programmable Gate Array Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of availability requires checking authorized distributors for remaining stock or last-time buy options. Ensure the specific suffix matches the required package and temperature grade, as variations exist within the ACT 1 family.

Field Programmable Gate Array Selection Notes

Select this part when 2000 equivalent gates and 547 CLBs are sufficient for the design. Verify that the 100-pin PQFP footprint fits the PCB layout constraints. Confirm that the 4.5V to 5.5V power supply aligns with the system requirements, as lower voltage variants may require different part numbers.

Field Programmable Gate Array Part Context

The A1020B belongs to the ACT™ 1 family, which succeeded earlier CMOS FPGA technologies. This series was designed to offer higher density and better performance than previous generations while maintaining compatibility with existing design tools. The 'B' suffix typically denotes a specific speed grade or revision within the ACT 1 lineup.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements are limited due to obsolescence. Consider migrating to the SmartFusion or IGLOO families for modern equivalents, though these require significant schematic and layout changes. No direct cross-reference is confirmed in public documentation.
