Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C) against the manufacturer's official datasheet. Confirm the BGA-165 package dimensions and pinout compatibility with the target PCB design. Ensure the 1.7V to 1.9V power supply requirements are strictly met to prevent operational instability or damage to the component.

Memory IC Selection Notes

Select this component when a 144 Mbit capacity with a 36-bit word width is required for parallel processing applications. The 450 MHz speed makes it suitable for high-throughput data paths. Consider the BGA-165 footprint for space-constrained designs. Verify that the system power delivery can support the peak current draw specified in the electrical characteristics table.

Memory IC Part Context

This part belongs to the SigmaDDR-II+ family of SRAMs from GSI Technology. These devices are engineered for high-density memory solutions in demanding electronic environments. The GS81302 series specifically targets applications needing robust data storage with fast read/write cycles, distinguishing itself through its wide operating temperature range and standardized parallel interface.

Memory IC Replacement Considerations

Cross-reference with other GS81302 variants such as GS81302D37AGD-450I for potential functional substitutes. Verify that any alternative maintains the same 4M x 36 organization and BGA-165 package to ensure mechanical and electrical compatibility without redesigning the host circuit board.
