Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature rating (-40°C to +85°C). Confirm the package type is BGA-165 and the interface is parallel. Ensure compatibility with 1.8V or 1.5V I/O levels as specified. Check RoHS compliance status before procurement.

Memory IC Selection Notes

Select this component when a 72 Mbit capacity with a 36-bit width is required. Choose based on the 400 MHz speed grade and industrial temperature range. Consider the BGA-165 footprint for PCB layout constraints. Verify voltage compatibility with the system's 1.8V or 1.5V domains.

Memory IC Part Context

This part belongs to the SigmaQuad-II family of QDR SRAMs from GSI Technology. These devices are designed for high-speed synchronous operation. The family offers various densities and speeds. This specific model provides a balance of density and performance for demanding digital signal processing tasks.

Memory IC Replacement Considerations

Check for other GS8662D36BGD variants with different speed grades or temperature ratings. Verify if the 'T' suffix indicates tape and reel packaging instead of tray. Ensure any substitute maintains the same 165-pin BGA footprint and electrical specifications.
