Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the official datasheet. Confirm the BGA-165 pinout matches the target PCB footprint. Ensure voltage requirements align with the 1.7V to 1.9V operating range specified for this variant.

Memory IC Selection Notes

Select this part when a 72 Mbit density with a 18-bit data width is required at 350 MHz speeds. Compare maximum current consumption of 705 mA against system power budgets. Ensure the design accommodates the BGA-165 package constraints and moisture sensitivity levels indicated in the specifications.

Memory IC Part Context

This component belongs to the SigmaDDR-II+ family of synchronous SRAMs from GSI Technology. These devices are designed to provide high bandwidth and low latency for demanding digital signal processing applications. The series offers various speed grades and organization options within a standardized package form factor.

Memory IC Replacement Considerations

Check for other speed grades within the GS8662T18BGD series, such as slower variants, if timing margins allow. Verify cross-compatibility with other GSI Technology SRAMs sharing the same BGA-165 footprint and electrical characteristics.
