Field Programmable Gate Array Procurement Notes

Verify the obsolete status of this component before initiating any procurement process. Confirm that the supplier can provide genuine units from existing stock or surplus channels, as standard manufacturing lines are discontinued. Ensure compliance with RoHS directives if required by the end application, noting that older batches may have different environmental certifications.

Field Programmable Gate Array Selection Notes

Select this FPGA when a non-volatile Flash-based solution is required for the ACT™ 1 family. Compare pin counts and I/O availability against alternative packages such as the VQFP variant if board space constraints differ. Verify that the commercial temperature range meets the operational requirements of the target environment.

Field Programmable Gate Array Part Context

This component belongs to the Microsemi ACT™ 1 series, which utilizes Flash technology for instant-on configuration without external memory devices. The A1020B model represents a specific gate count tier within this lineage, offering a balance of logic resources and I/O flexibility for embedded applications prior to the transition to more advanced FPGA architectures.

Field Programmable Gate Array Replacement Considerations

No direct public substitute part numbers are confirmed for this obsolete component. Designers should evaluate newer Microsemi SmartFusion or IGLOO families for functional equivalents, ensuring pin compatibility and logic resource adequacy.
