Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' against official Microsemi documentation to confirm the exact speed grade and commercial/industrial/military classification. Check for RoHS compliance status as older ACT 3 devices may not meet current environmental standards. Confirm availability through authorized distributors, noting that legacy FPGA families often have limited stock or end-of-life statuses. Ensure the package type matches the PCB footprint requirements precisely.

Field Programmable Gate Array Selection Notes

Select this part when designing systems requiring up to 4000 equivalent gates with guaranteed 110 MHz performance. Consider the ACT 3 family's compatibility with existing Microsemi design tools if migrating from similar devices. Evaluate the 160-pin I/O count against system interface needs. Compare against higher-density ACT 3 variants if more logic resources are anticipated. Verify thermal management capabilities for the 125 °C maximum junction temperature requirement.

Field Programmable Gate Array Part Context

This component is part of the Accelerator Series ACT 3 family, designed for high-speed logic applications. It succeeds earlier ACT series devices by offering improved predictability and faster clock-to-output times. The ACT 3 architecture provides dedicated flip-flops and fast clock networks. This specific model represents a mid-range density option within the PQFP package lineup, balancing resource capacity with pin count limitations.

Field Programmable Gate Array Replacement Considerations

Direct replacements include other ACT 3 family members such as the A1440A-1PQ160I for industrial temperature ranges. Cross-reference with Actel-branded equivalents if sourcing from legacy inventories. Verify pinout compatibility before substituting with different speed grades like the -1 variant. Consult Microchip PCNs for any package or material changes affecting form, fit, or function.
