Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I2LG' against official Intel/Altera documentation to confirm temperature grade and package variant. Ensure compatibility with existing board designs regarding the 1760-FBGA footprint and power delivery requirements for the 0.82V–0.88V core voltage range before ordering.

Field Programmable Gate Array Selection Notes

Select this model when high logic density (1.66M LEs) and significant I/O count (688) are required alongside secure data handling capabilities. Compare against the 1SG166HN1F43I2LG variant if different speed grades or specific packaging options are needed. Confirm that the 48-transceiver configuration meets the bandwidth requirements for the target application.

Field Programmable Gate Array Part Context

This component belongs to the Stratix 10 GX series, designed for high-performance computing and networking applications. It shares architectural similarities with other Stratix 10 devices but offers specific resource counts tailored for demanding digital signal processing and protocol conversion tasks.

Field Programmable Gate Array Replacement Considerations

Direct replacements within the same family include the 1SG166HN1F43I2LG. Verify pinout and electrical specifications carefully, as suffix changes may indicate differences in speed grading or environmental ratings rather than functional equivalence.
