A1425A-1PLG84C

Field Programmable Gate Array Overview

The A1425A-1PLG84C is an ACT3 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 2,500 system gates and 310 Logic/Configurable Logic Blocks (LABs/CLBs). The device provides 69 user-programmable I/O pins and operates within a supply voltage range of 4.5V to 5.5V. It is housed in an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads. The component supports surface-mount installation and functions within a commercial temperature range of 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• ACT3 architecture providing high-density programmable logic with 100% automatic place-and-route capabilities for predictable performance.
• Fast clock-to-output timing characteristics suitable for high-speed digital applications.
• Supports mixed-voltage operation with PCI-compliant I/O standards.

Field Programmable Gate Array Applications

• High-speed data processing and protocol conversion
• Custom logic acceleration in industrial control systems
• Interface bridging between legacy and modern digital components

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'C' against official Microsemi documentation to confirm the commercial temperature grade and lead finish specifications. Confirm RoHS compliance status as older ACT3 variants may not meet current environmental directives. Check for active obsolescence notices or last-time-buy dates from authorized distributors before procurement planning.

Field Programmable Gate Array Selection Notes

Select this model when 2,500 system gates and 69 I/Os are required in an 84-pin PLCC form factor. Ensure the design environment supports the 4.5V to 5.5V supply voltage range. Consider pin-locking features if deterministic timing is critical for the application. Verify that the 0°C to 70°C operating range meets the target system's thermal requirements.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT3 family, designed as a drop-in replacement for complex PLDs and ASICs. The ACT3 series emphasizes ease of integration and synthesis-friendly architecture. It allows up to 100% resource utilization and offers unique in-system diagnostic capabilities through Silicon Explorer II tools.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same package are limited due to the discontinued status of the ACT3 line. Evaluate newer Microsemi SmartFusion or IGLOO2 families for functional equivalents, noting significant differences in I/O voltage levels, pin counts, and programming interfaces.
