Field Programmable Gate Array Procurement Notes

Verify the specific suffix 'I2LG' against official Intel/Altera documentation to confirm the exact speed grade, temperature rating, and packaging variant. Ensure compatibility with required configuration modes and power delivery specifications before procurement.

Field Programmable Gate Array Selection Notes

Select this model for designs requiring high logic density combined with significant embedded memory resources. Verify that the PCB layout supports the 1760-ball FCBGA footprint and that the power supply design accommodates the specified core voltage range of 770 mV to 970 mV.

Field Programmable Gate Array Part Context

This part belongs to the Intel Stratix 10 family, specifically the TX sub-family optimized for high-speed serial communications. It shares architectural similarities with other 850K devices in the series but differs in package type and specific speed binning defined by the ordering suffix.

Field Programmable Gate Array Replacement Considerations

Direct pin-to-pin replacements within the same package and logic density should be sought from the Stratix 10 TX 850 family. Verify that any substitute part matches the 1760-ball FCBGA form factor and meets the 28.3 Gb/s transceiver requirements.
