EPXA4F1020C1

Overview

The Altera EPXA4F1020C1 is an Excalibur embedded processor device featuring an ARM926EJ-S core integrated with a programmable logic fabric. It utilizes a 1020-pin FineLine BGA package and operates within a commercial temperature range of 0°C to 70°C. The component supports system-on-a-programmable-chip integration, combining high-density logic resources with embedded memory blocks for complex digital signal processing and control applications.

Feature Summary

• Integrates an ARM926EJ-S processor core directly into the FPGA fabric for tight coupling between software execution and hardware acceleration.
• Provides high-density programmable logic resources suitable for implementing complex custom peripherals and interface protocols.
• Includes embedded memory blocks to support data buffering and instruction storage without external components.

Applications

• Embedded systems requiring combined processing and reconfigurable logic capabilities
• Industrial automation controllers with specific interface requirements
• Telecommunications equipment utilizing custom protocol implementations

Procurement Notes

Verify the specific suffix codes against official Intel/Altera documentation to confirm voltage levels and temperature ratings. Confirm RoHS compliance status as legacy Excalibur devices may have varying environmental certifications depending on manufacturing date. Ensure design files are compatible with current Quartus Prime versions supporting this legacy architecture.

Selection Notes

Select this component when an application demands a tightly coupled processor and FPGA on a single die. Evaluate pin count requirements against the 1020-pin footprint. Consider power consumption profiles relative to the ARM9 core activity and logic utilization. Verify that the available I/O banks meet the voltage standards of connected peripherals.

Part Context

This device belongs to the Excalibur family, which was designed to merge ARM processor technology with Altera's FPGA capabilities. It represents a System-on-Programmable-Chip (SOPC) solution intended to reduce board space and interconnect complexity compared to discrete processor and FPGA combinations.

Replacement Considerations

Check for direct successors in the Arria or Stratix families if higher performance is needed. Legacy support for older Excalibur devices may require verification of toolchain compatibility and long-term availability constraints.
