EPXA4F672C3

Overview

The Altera EPXA4F672C3 is an Excalibur FPGA integrating an ARM9 processor core with programmable logic fabric. It utilizes a 672-pin FBGA package and operates within a supply voltage range of 1.15V to 1.25V. The device supports industrial temperature ranges from 0°C to 85°C junction temperature. Key specifications include 3158 LABs, 50,528 logic elements, and 594,432 total RAM bits. It provides 450 I/O pins for system connectivity.

Feature Summary

• Integrates an ARM9 processor core directly onto the FPGA die for embedded control applications.
• Supports high-speed network communication protocols such as FlexRay CC and BG.
• Provides substantial programmable logic resources via the Excalibur architecture.

Applications

• Robot system implementation
• Automotive network communication systems
• Embedded control systems requiring integrated processing and logic

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix C3 matches required speed grades and temperature ratings. Check for End-of-Life (EOL) status or last-time-buy notices, as this is a legacy Excalibur device. Ensure compatibility with legacy Quartus software versions if updating existing designs.

Selection Notes

Select this component when an integrated ARM9 processor is required alongside significant FPGA logic capacity. It is suitable for applications needing deterministic real-time control combined with flexible digital logic. Consider the 672-pin BGA footprint for PCB layout constraints. Evaluate power consumption against the 1.15V-1.25V supply requirements.

Part Context

This part belongs to the Altera Excalibur family, which combines ARM9 processors with FPGA fabric. It represents a generation of devices designed for complex embedded systems before the transition to newer Cyclone and Arria families. The EPXA4 variant specifically targets applications requiring both processing and reconfigurable logic in a single package.

Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Legacy Excalibur devices may require migration to modern Intel/Altera FPGA families with embedded processors, such as Agilex or Stratix, depending on performance needs.
