Procurement Notes

Verify the specific suffix codes against official Intel documentation to confirm exact speed grades and commercial temperature ratings. Ensure compatibility with required PCB fabrication processes for the 1760-ball FCBGA package. Confirm that the selected variant meets all environmental specifications for the intended deployment environment before finalizing orders.

Selection Notes

Select this component when a balance of moderate logic density and significant embedded memory is required. The Stratix 10 SX series offers lower power consumption compared to GX variants while maintaining robust processor integration. Evaluate the 68 Mbit memory capacity against application requirements to ensure sufficient on-chip storage for buffers and firmware.

Part Context

This part belongs to the Stratix 10 SX family, which targets cost-sensitive applications requiring SoC capabilities. It shares the same physical package dimensions as other devices in the 1760-FBGA form factor but differs in internal resource allocation and performance characteristics. The SX series complements the higher-performance GX and GT families by focusing on efficient logic-to-memory ratios.

Replacement Considerations

Direct replacements within the same package include the 1SX085HN2F43E2VG and 1SX085HN3F43E2VG. These variants offer different speed grades or extended temperature ranges. Verify pinout compatibility and electrical specifications before substituting to ensure functional equivalence in the target design.
