Procurement Notes

Verify the specific speed grade suffix corresponding to the 'I6' designation against official datasheet tables to ensure timing compliance. Confirm that the 672-pin FineLine BGA package dimensions match the system board layout requirements. Ensure design tools are compatible with the Stratix GX family specifications.

Selection Notes

Select this device when designs require vertical migration capabilities within the 672-pin package, allowing transitions between EP1SGX10C and EP1SGX25C densities. Evaluate the required number of transceiver channels, as this density supports varying channel counts depending on the specific sub-model variant. Consider the available I/O pin counts for source-synchronous interfaces when planning peripheral connections.

Part Context

The Stratix GX family represents Altera's second FPGA generation to combine high-performance logic arrays with embedded high-speed serial transceivers. This family utilizes a 1.5-V logic array technology designed for scalability and time-to-market efficiency. The EP1SGX25 variant sits within the mid-range density offerings of this architecture.

Replacement Considerations

Vertical migration within the same package allows designers to move between EP1SGX10C and EP1SGX25C devices provided dedicated configuration and power pins remain consistent. Cross-referencing I/O pin availability is necessary when migrating across different densities within the 672-pin FineLine BGA form factor.
