• Automotive electronics applications within specified temperature ranges
• Telecommunications infrastructure equipment

Field Programmable Gate Array Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of availability should focus on authorized distributors holding remaining stock or qualified second-source suppliers. Ensure that any sourced units match the original Microsemi manufacturing specifications and have not been subject to unauthorized modifications. Confirm the specific suffix 'I' denotes the correct industrial temperature grade required for the application.

Field Programmable Gate Array Selection Notes

When selecting this FPGA, verify that the 2,500 gate count and 80 I/O limit meet the design requirements. The 100-BQFP package must be compatible with the PCB footprint. Consider the 4.5V to 5.5V power supply requirement for system design. Compare against newer ACT3 variants if higher density or different packaging options are needed for future scalability.

Field Programmable Gate Array Part Context

The A1425A-1PQG100I belongs to the Microsemi ACT3 family, which bridges the gap between PLDs and larger FPGAs. This series is known for its predictable performance and fast place-and-route times. The part number indicates the 1 speed grade and industrial temperature variant within the broader A1425 product line.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package may include other ACT3 devices such as the A1425A-PQG100I, though verification of speed grades and temperature ratings is essential. Cross-family migration to ProASIC3 or SmartFusion may require schematic and layout redesign.
