Memory IC Procurement Notes

Verify the specific suffix 'D75A' against official Micron documentation to confirm pinout compatibility and electrical characteristics. Ensure the source provides valid RoHS compliance statements and traceability records. Confirm availability status directly with authorized distributors as lead times may vary significantly for legacy components.

Memory IC Selection Notes

Select this component when a parallel NOR interface is required for direct code execution. The 64 Mbit capacity suits applications needing moderate storage density. Verify that the 75 ns speed meets the processor's timing requirements. Ensure the operating voltage aligns with the system's power supply rails.

Memory IC Part Context

This part belongs to the Micron J3 series of NOR Flash memories. These devices are designed for high-reliability embedded applications. The series offers a balance of density and speed suitable for firmware storage. The TSOP-56 package allows for compact board designs in space-constrained environments.

Memory IC Replacement Considerations

Check for JEDEC standard compatible parts from other manufacturers offering identical pinouts and specifications. Verify electrical parameters such as access time and voltage ranges before substitution. Consult Micron's cross-reference tools for officially recommended alternatives.
