Memory IC Procurement Notes

Verify the specific suffix '633I' against official GSI Technology documentation to confirm the 633 MHz speed grade and industrial temperature rating. Ensure compatibility with the 1.7V to 1.9V power supply requirements and 165-ball BGA footprint during procurement planning. Cross-reference datasheet revisions to validate electrical characteristics and pin assignments before finalizing orders.

Memory IC Selection Notes

Select this component when system designs require high-frequency parallel SRAM operation up to 633 MHz within industrial thermal constraints. Compare against lower speed variants like the 500 MHz model if thermal management or power consumption limits are critical. Confirm that the 8M x 18 bit organization aligns with the target memory map and that the BGA-165 package fits the available PCB real estate.

Memory IC Part Context

This part belongs to the GS81302D20AGD series of SigmaQuad-II+ memories. It shares the same physical package and basic organization as other speed grades but offers higher throughput capabilities. The 'I' suffix denotes industrial temperature capability, distinguishing it from commercial grade counterparts. It represents a specialized solution for applications needing robust performance under varying environmental conditions.

Memory IC Replacement Considerations

Direct substitutes include other speed grades within the GS81302D20AGD family, such as the GS81302D20AGD-500, provided the lower clock frequency meets system timing requirements. Verify that alternative parts maintain the same 165-ball BGA footprint and voltage specifications to ensure mechanical and electrical compatibility without redesigning the host board.
