Memory IC Procurement Notes

Verify the specific memory density configuration during procurement, as datasheet references indicate potential variations between 4M x 18 and 8M x 18 organizations for this part number series. Confirm the operating temperature grade matches the industrial requirement (-40°C to +100°C). Ensure the package type is correctly identified as TQFP-100 for PCB layout compatibility. Cross-reference the manufacturer's latest documentation to confirm current production status and lead times.

Memory IC Selection Notes

Select this component when a synchronous SRAM with 18-bit data width and high clock speeds is required. The industrial temperature rating makes it suitable for harsh environments. Compare against other members of the GS81280Z18GT family if different speed grades or voltage levels are needed. Ensure the system design accommodates the parallel interface requirements and the specific power consumption characteristics associated with the 333 MHz operation mode.

Memory IC Part Context

This device belongs to the GS81280Z18GT series of NBT SRAMs from GSI Technology. The series includes variants with different speed grades, such as the 400 MHz version, and different organizational structures. The 'I' suffix typically denotes the industrial temperature range extension. These components are designed to replace older asynchronous memories in high-speed digital signal processing and networking applications.

Memory IC Replacement Considerations

Direct substitutes include other parts within the GS81280Z18GT series, such as the GS81280Z18GT-400I for higher speed requirements. Verify pinout compatibility and electrical specifications before substitution.
