EPXA10F1020C2

Overview

The Altera EPXA10F1020C2 is a System-on-a-Programmable-Chip (SoPC) device from the Excalibur family, integrating an ARM922T processor with programmable logic. It features a 32-bit RISC core operating at up to 200 MHz, equipped with an MMU and separate 8-Kbyte instruction and data caches. The PLD fabric provides 38,400 logic elements, 256 Kbytes of single-port SRAM, and 128 Kbytes of dual-port SRAM. External memory support includes SDRAM controllers for up to 512 Mbytes and an expansion bus interface. The device utilizes a 1020-pin FineLine BGA package.

Feature Summary

• ARM922T 32-bit RISC processor core with MMU and Harvard cache architecture
• 38,400 logic elements and up to 256 Kbytes internal single-port SRAM
• Embedded SDRAM controller supporting SDR and DDR standards up to 512 Mbytes
• Advanced bus architecture based on AMBA AHB with bidirectional bridges

Applications

• Voice-over packet gateway systems
• Real-time spoken language translation devices
• Compute-intensive embedded applications requiring high data bandwidth

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated in specific ordering suffixes. Ensure compatibility with legacy development tools such as SOPC Builder and Quartus II for system integration.

Selection Notes

Select this model when a combined ARM processor and large PLD fabric are required within a single chip. The EPXA10 offers the highest gate count and memory resources in the Excalibur family. Consider the 1020-pin package constraints and 1.8-V supply voltage requirements during PCB layout.

Part Context

The EPXA10 belongs to the Excalibur family, which merges ASIC-level integration with FPGA flexibility. It succeeded earlier APEX devices by adding embedded processing capabilities. This family represents a transition toward structured SoPC designs before the introduction of Nios processors.

Replacement Considerations

No direct public substitute part numbers are documented. Modern equivalents may include Stratix or Arria series FPGAs with embedded ARM cores, though architectural differences require full design re-evaluation.
