Memory IC Procurement Notes

Verify the specific suffix 'I' confirms industrial temperature rating (-40°C to +100°C) against the manufacturer datasheet. Confirm BGA-119 package dimensions and moisture sensitivity levels prior to PCB design. Ensure power supply specifications match the 2.3 V to 3.6 V operating range defined in the official documentation.

Memory IC Selection Notes

Select this component when high-density 18-bit wide memory is required at 250 MHz speeds. The NBT architecture offers superior throughput compared to traditional synchronous SRAMs. Verify compatibility with existing system voltage rails and ensure the BGA-119 footprint aligns with board layout constraints.

Memory IC Part Context

This part belongs to the GS82564Z18GB series of NBT SRAMs from GSI Technology. These devices are designed for high-performance embedded applications requiring fast random access. The series utilizes advanced CMOS technology to deliver low power consumption while maintaining high-speed operation across commercial and industrial temperature ranges.

Memory IC Replacement Considerations

Check for pin-compatible alternatives within the same GS82564Z family that may offer different speed grades or voltage options. Verify that any substitute maintains the 16 M x 18 organization and BGA-119 package type.
