Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature grade (-40°C to +85°C) against the manufacturer's official datasheet. Confirm the pinout compatibility with the target PCB footprint, as BGA packages require precise alignment. Check for RoHS compliance status directly from the supplier documentation. Ensure ESD handling procedures are followed during installation due to moisture sensitivity classification.

Memory IC Selection Notes

Select this component when a 72 Mbit capacity with 18-bit word width is required for QDR applications. The 357 MHz speed grade offers higher throughput compared to lower-frequency variants in the same series. Consider the 165-ball BGA package constraints for board space and thermal management. Evaluate power consumption limits against available supply rails, noting the 1.8V core voltage requirement.

Memory IC Part Context

This part belongs to the SigmaQuad-II+ family of QDR SRAMs from GSI Technology. It shares the same physical package and basic interface protocol with other members like the GS8662Q36BGD series but differs in data width and organization. The family is designed for applications demanding high bandwidth and low latency without the complexity of DRAM refresh cycles.
