Field Programmable Gate Array Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Microsemi. Verification of authenticity is critical when sourcing from secondary markets, as availability is limited to surplus stock. Buyers should confirm the specific suffix '1' indicates the required speed grade against original datasheets before procurement.

Field Programmable Gate Array Selection Notes

Engineers selecting this part must account for its obsolete status and plan for long-term supply risks. The ACT™ 2 series serves as a legacy option; modern replacements may require architectural adjustments. Verify that the 100-PQFP package dimensions and pinout match the existing PCB layout constraints strictly.

Field Programmable Gate Array Part Context

The A1225A-1PQ100C is part of the broader ACT™ 2 FPGA portfolio, which bridges the gap between simple PLDs and larger FPGAs. This specific model offers a balance of logic density and I/O flexibility, historically utilized in telecommunications and industrial control systems requiring reliable, reprogrammable logic solutions.

Field Programmable Gate Array Replacement Considerations

Microsemi recommends evaluating the A42MX or A5400 families as potential successors. These newer architectures offer enhanced performance and security features while maintaining compatibility with existing design tools where applicable.
