Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the extended industrial temperature rating of -40°C to +100°C against the official datasheet. Confirm the BGA-165 package dimensions match your PCB footprint requirements. Ensure the 2.5V/3.3V dual-voltage capability aligns with your system's core supply specifications before finalizing procurement.

Memory IC Selection Notes

Select this component when a high-density 144 Mbit SRAM with 250 MHz synchronous performance is required. It is suitable for designs needing both pipeline and flow-through operational modes. Consider the BGA-165 form factor for compact layouts. Verify that the 490 mA peak current draw fits within your power budget constraints.

Memory IC Part Context

This part belongs to the GS81282Z18GD series of NoBL™ and ZBT™ SRAMs. These devices are designed for high-performance embedded memory applications. The series offers various speed grades and organizations, providing scalability for different bandwidth requirements while maintaining compatibility with standard interfaces.

Memory IC Replacement Considerations

Check for other speed grades within the GS81282Z18GD family, such as the -200I variant, if lower power consumption is prioritized over the 250 MHz maximum frequency. Ensure any substitute maintains the same BGA-165 package and 8M x 18 bit organization.
