Procurement Notes

Verify the specific suffix 'N' against official Intel/Altera documentation to confirm RoHS compliance status, as historical datasheets may list varying environmental certifications. Confirm the package type is strictly 672-BBGA (27x27 mm) during mechanical integration. Ensure power delivery circuits support the 1.425 V to 1.575 V range required for stable operation.

Selection Notes

Select this model when designs require approximately 25K logic elements combined with substantial embedded RAM capacity. The Stratix GX series is suitable for applications needing parallel processing capabilities at system clock speeds such as 125 MHz. Compare against lower-density Stratix variants if resource utilization is below 20K LEs to optimize cost and board space.

Part Context

This component is part of the Stratix GX family, which was engineered for high-performance networking and industrial applications. The EP1SGX25DF672C7N specifically addresses needs for robust error correction coding and high-throughput data handling. It represents a generation of FPGAs that integrated significant on-chip memory to reduce external memory dependencies in communication protocols.

Replacement Considerations

Direct pin-to-pin replacements are not publicly documented for this legacy part number. Designers should evaluate migration paths to newer Intel Agilex or Stratix 10 families, noting that architectural differences require schematic and layout revisions rather than simple substitution.
