Procurement Notes

Verify the specific suffix codes against official Intel/Altera documentation to confirm temperature range and package variations. Confirm moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure compatibility with the latest Quartus Prime software versions for programming and configuration. Check for any recent Product Change Notifications regarding labeling or material composition updates.

Selection Notes

Select this model when a combined ARM processor and FPGA fabric is required in a compact 35x35 mm footprint. Compare logic element counts and transceiver availability against larger Stratix 10 variants if higher density is needed. Verify that the 1.5 GHz speed grade meets your timing constraints. Consider power consumption profiles relative to the thermal solution available in the target enclosure design.

Part Context

This component belongs to the Stratix 10 SX family, designed for cost-sensitive applications requiring embedded processing alongside programmable logic. It shares the same package outline as other 1152-ball devices in the series but differs in internal resource allocation. The SX variant typically offers lower transceiver counts compared to the GX series, focusing on general-purpose I/O and embedded ARM cores.

Replacement Considerations

Direct functional replacements within the same package include 1SX065HH3F35E2LG and 1SX065HH2F35E2VG. These parts share identical pinouts and core specifications but may differ in temperature grades or manufacturing revisions. Validate electrical characteristics and software compatibility before substitution.
