Procurement Notes

Verify the specific suffix 'I2' confirms industrial temperature rating (-40°C to 100°C) and 'LG' indicates the lead-free green package variant. Confirm moisture sensitivity level (MSL 3) handling requirements during assembly. Ensure compatibility with Quartus Prime software versions supporting the Stratix 10 SX family. Check for any recent Product Change Notifications regarding marking or packaging updates before finalizing orders.

Selection Notes

Select this model when both high-end FPGA fabric performance and embedded ARM processing are required in a single device. Compare against the GX series if lower power consumption is prioritized over the specific SX feature set. Verify that the 1760-ball package fits the target board layout constraints. Ensure design tools support the specific speed grade associated with the part number.

Part Context

This component belongs to the Intel (formerly Altera) Stratix 10 SX family, designed for cost-sensitive yet high-performance applications. It combines the programmability of FPGAs with the efficiency of embedded processors. The SX series targets markets such as telecommunications, industrial, and medical sectors where system integration and reduced bill-of-materials are critical design drivers.

Replacement Considerations

Direct functional replacements within the same package and pinout are limited due to the specific speed grade and temperature rating. Consider the 1SX085HN2F43I2LG for identical electrical characteristics but potentially different manufacturing date codes or minor revision differences. Cross-family migration to Agilex devices requires significant redesign.
