Memory IC Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct speed grade and temperature rating compatibility. Confirm that the BGA-165 footprint matches your PCB design constraints. Check for moisture sensitivity levels and reflow soldering profile requirements prior to assembly. Ensure supply chain sources provide genuine components with traceable manufacturing dates.

Memory IC Selection Notes

Select this component when system designs require 144 Mbit density with 500 MHz throughput capabilities. Consider the 1.8V nominal operating voltage for power budget calculations. Evaluate the BGA-165 package size against available board real estate. Compare thermal performance characteristics against the specified 100°C maximum junction temperature limit for your enclosure environment.

Memory IC Part Context

This part is part of the GS81302 series of DDR SRAMs from GSI Technology. It shares architectural similarities with other members like the GS81302DT20E-500I but differs in interface type and speed grade. The series targets bandwidth-intensive applications where latency and throughput are critical performance metrics.

Memory IC Replacement Considerations

Consult official substitution guides for compatible alternatives within the same product family. Verify pinout and electrical parameter compatibility before replacing existing inventory.
