Procurement Notes

Verify the specific suffix 'LGAS' against official manufacturer documentation to confirm package type and environmental rating. Ensure compatibility with existing board layouts for the 1760-ball FBGA footprint. Confirm moisture sensitivity level handling procedures during assembly to prevent damage. Cross-reference the revision history in the datasheet for any recent manufacturing changes.

Selection Notes

Select this model when both high-end FPGA logic resources and an embedded ARM processor are required on a single die. Compare against the GX series if transceiver speed is the primary constraint rather than embedded processing. Evaluate power consumption profiles against thermal management capabilities of the target enclosure. Verify that the 68 Mbit embedded memory meets the application's buffer requirements.

Part Context

This component belongs to the Stratix 10 SX series, which is optimized for systems combining high-performance logic with embedded processing. It shares the same physical package dimensions as other variants in the 1760-ball FBGA form factor but differs in internal resource allocation and processor integration compared to pure FPGA models.

Replacement Considerations

Direct functional substitutes within the same package include the 1SX085HN2F43I2VGAS and 1SX085HN2F43I2LG. These parts share identical pinouts and core specifications, differing primarily in packaging or regional distribution codes. Verify electrical parameters match before substitution.
