Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix against official Intel/Altera documentation to confirm package type, speed grade, and operating temperature range. Ensure power supply designs accommodate the specified 0.82V–0.88V core voltage requirements. Confirm moisture sensitivity level (MSL 3) handling procedures during assembly to prevent damage.

Field Programmable Gate Array Selection Notes

Select this model when designing systems requiring 1.66M logic elements and 688 I/Os in an FCBGA form factor. Verify that the application environment stays within the -40°C to 100°C junction temperature limit. Ensure the board layout supports the 1760-ball package dimensions and thermal dissipation needs for 48 high-speed transceivers.

Field Programmable Gate Array Part Context

This component belongs to the Stratix 10 GX family, designed for high-performance networking and compute applications. It shares the 1760-FBGA package and 688 I/O count with other variants in the series, such as the 1SG110HN1F43I2LG, but offers higher logic density and distinct memory configurations compared to lower-end models like the 1SG085HN2F43I2LG.

Field Programmable Gate Array Replacement Considerations

Direct functional substitutes within the same package and pinout include other Stratix 10 GX devices with matching I/O counts, such as 1SG110HN1F43I2LG or 1SG085HN2F43I2LG, provided logic capacity and memory requirements are met.
