Procurement Notes

Verify the specific suffix codes against official Intel/Altera documentation to confirm pinout compatibility and electrical characteristics. Ensure that the ordering information matches the required package type and operating temperature range before finalizing procurement orders.

Selection Notes

Select this component when a combination of significant FPGA fabric resources and embedded ARM processing capabilities is required. Consider the 1760-ball BGA package constraints and ensure the design supports the necessary power delivery network for the integrated processor subsystem.

Part Context

This part belongs to the Stratix 10 SX family, which targets cost-sensitive applications compared to the GX series. It shares the same core architecture but differs in transceiver counts and memory configurations. The HN3 designation indicates specific speed grades and package options within the 2800K density tier.

Replacement Considerations

Direct replacements are limited within the same density tier. Verify compatibility with Agilex 5 devices for future-proofing, noting architectural differences. Cross-reference with other Stratix 10 SX variants like 1SX280HN3F43E2VGS2 only if pin-to-pin and feature parity is confirmed by datasheets.
