Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the extended industrial temperature range (-40°C to +100°C) compared to commercial variants. Confirm the 'GD' designation aligns with the required BGA-165 package and lead finish specifications. Ensure the 633 MHz speed grade matches system timing requirements. Cross-reference the manufacturer part number with official GSI Technology documentation to validate availability and revision status before procurement.

Memory IC Selection Notes

Select this component when high-bandwidth parallel memory is required for networking or telecom applications. The 4 M x 36 organization suits wide-data-path architectures. The industrial temperature range is critical for harsh environments. Compare against other GS81302 variants based on speed grade and temperature rating to ensure compatibility with existing board designs and thermal constraints.

Memory IC Part Context

This part belongs to the GS81302D38AGD family of SigmaQuad-II+ SRAMs. It shares the 144 Mbit capacity and 4 M x 36 organization with other members like the GS81302D38AGD-633. The primary differentiator is the '-I' suffix indicating industrial temperature capability and the '-633' indicating the 633 MHz speed bin. It represents a high-performance solution within GSI's QDR portfolio.

Memory IC Replacement Considerations

Direct substitutes include other GS81302D38AGD variants with matching pinouts and electrical characteristics. Verify that any replacement maintains the 633 MHz speed grade and industrial temperature range if those are strict requirements. Check for minor revisions in the datasheet that might affect timing parameters.
