Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +100°C) against the official datasheet. Confirm the BGA-165 package dimensions and pinout match the target PCB footprint. Ensure the 2.5V/3.3V dual-voltage capability aligns with the system power rails. Check for moisture sensitivity level requirements during storage and handling.

Memory IC Selection Notes

Select this component when a 288 Mbit capacity with 18-bit word width is required. The 400 MHz speed class suits applications needing rapid data throughput. Consider the BGA-165 form factor for space-constrained designs. Verify that the system can support the specified current consumption levels at the chosen operating voltage.

Memory IC Part Context

This part belongs to the GS8256418GD series of SyncBurst SRAMs. It shares the 16M x 18 organization with other variants like the GS8256418GD-200I but offers higher performance. The series is designed for pipeline/flow-through operations, distinguishing it from lower-speed asynchronous alternatives within the broader memory portfolio.

Memory IC Replacement Considerations

The GS8256418GD-200I is a confirmed slower variant within the same series. Cross-referencing with other manufacturers requires verifying pin compatibility and electrical specifications.
