Memory IC Procurement Notes

Verify the exact suffix 'I' corresponds to the industrial temperature grade (-40°C to +85°C) as specified in the official datasheet. Confirm that the 119-pin BGA footprint matches your PCB design constraints. Ensure power supply decoupling meets the high peak current demands indicated in the electrical specifications. Check for RoHS compliance status if required by your manufacturing standards.

Memory IC Selection Notes

Select this component when a wide 36-bit data path is necessary for high-throughput applications. The 333 MHz speed class offers a balance between performance and power consumption compared to faster variants. Consider the 119-BGA package size for space-constrained designs. Verify compatibility with existing system voltage levels, as the device supports a broad range from 2.3V to 3.6V.

Memory IC Part Context

This part belongs to the GS8322Z36AGB series of NoBL SRAMs from GSI Technology. These devices are designed to replace traditional ZBT and pipeline SRAMs while offering superior bus efficiency. The series includes various speed grades and package options, with the GB suffix indicating the 119-pin BGA form factor. It is part of a family pin-compatible with other densities in the same series.

Memory IC Replacement Considerations

Direct substitutes include other GS8322Z36AGB variants with different speed grades (e.g., -250IV, -200IV) if lower performance is acceptable. Ensure any replacement maintains the 119-pin BGA footprint and 1M x 36 organization. Verify that the alternative part supports the required industrial temperature range and voltage specifications.
