Memory IC Procurement Notes

Verify the specific suffix 'GD' against official datasheets to confirm pinout and electrical characteristics, as variations exist within the series. Ensure compatibility with the target board's thermal management capabilities given the power consumption specifications. Confirm moisture sensitivity level handling procedures during assembly to prevent damage. Cross-reference the manufacturer's latest documentation for any updates to the recommended operating conditions.

Memory IC Selection Notes

Select this component when a 400 MHz synchronous SRAM with 18-bit width is required. Compare against the GS82564Z18GB-400I if a different package type like BGA-119 is preferred. Consider the GS82564Z18GD-250IV for lower speed requirements with extended temperature ranges. Evaluate power consumption limits against available supply rails before finalizing the design.

Memory IC Part Context

This part belongs to the GS82564Z18GB/GD family of NBT SRAMs from GSI Technology. These devices are designed for demanding embedded applications requiring low latency and high bandwidth. The family shares common architectural features but differs in packaging and specific timing parameters. This model represents a high-speed variant optimized for synchronous bus interfaces.

Memory IC Replacement Considerations

GS82564Z18GB-400I offers similar electrical performance but uses a BGA-119 package instead of BGA-165. GS82564Z18GD-250I provides a slower 250 MHz option with potentially different thermal characteristics. Verify mechanical footprint compatibility before substituting.
