Memory IC Procurement Notes

Verify the specific voltage variant, as the suffix IV indicates a particular supply range within the series. Confirm RoHS compliance status if lead-free construction is required for assembly processes. Check moisture sensitivity level requirements for surface mount reflow profiles. Ensure the 119-pin BGA footprint matches the target PCB design constraints.

Memory IC Selection Notes

Select this component when a 36-bit wide synchronous SRAM is needed at 250 MHz speeds. The NBT feature distinguishes it from standard ZBT parts by eliminating turnaround delays. Consider the industrial temperature rating for harsh environments. Verify that the 1.8V or 2.5V core voltage aligns with the system power rails.

Memory IC Part Context

This part belongs to the GS8322Z36AGB series of No Bus Turnaround SRAMs manufactured by GSI Technology. These devices are designed to maximize bus bandwidth compared to traditional ZBT SRAMs. The series offers various speed grades and packaging options, with this specific model providing a balance of performance and industrial reliability.

Memory IC Replacement Considerations

Check for direct substitutes within the GS8322Z series with different speed grades like -200 or -333 variants. Verify pin compatibility with other NBT or ZBT SRAM families such as NtRAM or NoBL if migrating designs.
