A1425A-1PQG100C

Field Programmable Gate Array Overview

The A1425A-1PQG100C is an Actel ACT3 field-programmable gate array (FPGA) manufactured by Microsemi Corporation. It features a logic density of 2,500 gates organized into 310 LAB/CLB blocks and provides 80 user-accessible I/O pins. The device operates within a supply voltage range of 4.5V to 5.5V and is housed in a 100-pin PQFP package with dimensions of 20x14 mm. It supports surface mount installation and functions reliably across a commercial temperature range of 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• Supports rapid prototyping and low-volume production as a non-volatile FPGA solution
• Integrates high-density programmable logic with extensive I/O capabilities for system integration
• Utilizes Actel's proven flash-based technology for instant-on functionality without external configuration memory

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic timing and robust logic processing
• Telecommunications infrastructure equipment for signal routing and protocol handling
• Automotive electronics applications operating within standard commercial temperature limits

Field Programmable Gate Array Procurement Notes

Verify component authenticity through authorized Microsemi distributors or certified secondary market suppliers due to the part's discontinued status. Confirm that the specific suffix 'C' denotes the commercial temperature grade and 'PQG100' indicates the plastic quad flatpack package variant. Request full traceability documentation and lot codes to ensure compliance with quality standards for legacy hardware replacement projects.

Field Programmable Gate Array Selection Notes

Select this component when a moderate logic density of 2,500 gates is sufficient for the design requirements. Ensure the application environment remains within the 0°C to 70°C operating range. Verify that the 100-pin PQFP footprint aligns with existing PCB layouts. Consider the 80 I/O count against interface needs, noting that higher pin counts are available in larger packages within the same ACT3 family.

Field Programmable Gate Array Part Context

This part belongs to the Actel ACT3 series, a line of flash-based FPGAs known for their non-volatile architecture. The ACT3 family bridges the gap between complex PLDs and larger FPGAs, offering immediate power-up readiness. The A1425A variant specifically targets applications needing reliable, reprogrammable logic without the overhead of external configuration devices common in volatile FPGA technologies.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements may be limited due to the discontinued nature of the ACT3 series. Evaluate newer Microsemi SmartFusion or IGLOO2 families for functional equivalents, though these require significant schematic and layout modifications. Cross-reference with other manufacturers' similar gate-count FPGAs only if package compatibility and electrical characteristics can be strictly matched.
