A14V25A-PLG84C

Field Programmable Gate Array Overview

The A14V25A-PLG84C is an ACT3 series Field Programmable Gate Array (FPGA) manufactured by Microsemi Corporation. It features 310 Configurable Logic Blocks (CLBs) and approximately 2,500 equivalent system gates. The device operates on a single 5V supply voltage within the 4.5V to 5.5V range. It is housed in an 84-pin Plastic Leaded Chip Carrier (PLCC) package with J-leads. The component supports a maximum operating frequency of 110 MHz and is rated for commercial temperature ranges from 0°C to 70°C.

Field Programmable Gate Array Feature Summary

• ACT3 architecture providing high-density logic resources in a compact form factor
• CMOS technology enabling reliable operation at standard 5V logic levels
• Supports complex digital design implementation through programmable interconnects

Field Programmable Gate Array Applications

• Industrial control systems requiring deterministic logic processing
• Communication interface protocols and signal conversion
• Automotive electronic control units (ECUs)

Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'PLG84C' against official Microsemi documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as older ACT3 variants may not meet current environmental directives. Check for End-of-Life (EOL) notifications or Last Time Buy dates before committing to production volumes.

Field Programmable Gate Array Selection Notes

Select this component when a moderate gate count around 2,500 is sufficient for the design. Ensure the application requires 5V I/O compatibility rather than lower voltage standards. Consider the PLCC package constraints regarding PCB space and reflow soldering profiles compared to surface-mount alternatives like QFP or BGA.

Field Programmable Gate Array Part Context

This part belongs to the Microsemi ACT3 family, designed as a drop-in replacement for various PALs and GALs while offering significantly higher complexity. It utilizes Actel's patented anti-fuse technology, which provides non-volatile configuration and inherent security against reverse engineering. The family bridges the gap between simple CPLDs and larger FPGAs.

Field Programmable Gate Array Replacement Considerations

Direct functional replacements are limited due to the proprietary anti-fuse nature of the ACT3 architecture. Review the A1425A or A1440A for similar gate counts, though pinouts will differ. Modern FPGA families from Xilinx or Lattice require significant schematic and bitstream redesign.
