Memory IC Procurement Notes

Verify the specific ordering suffix against official Micron documentation to confirm package type and temperature rating. Ensure compatibility with system voltage requirements before integration. Confirm end-of-life status and availability through authorized distributors. Validate that the component meets AEC-Q100 standards if used in automotive environments.

Memory IC Selection Notes

Select this component for applications requiring automotive-grade reliability and high-speed memory access. Consider the 16-bit interface width and TSOP packaging constraints during PCB layout. Evaluate power consumption profiles against system thermal limits. Ensure the controller supports DDR SDRAM protocols and SSTL_2 signaling standards.

Memory IC Part Context

This part belongs to Micron's 256Mb DDR SDRAM family designed for automotive use. It shares architectural similarities with other x16 variants but differs in package and speed grade. The P suffix indicates a lead-free TSOP package, while :M denotes the revision level. It complements lower-density options for scalable memory designs.

Memory IC Replacement Considerations

Direct replacements must match the 16-bit width, 256Mb density, and TSOP-66 package. Verify timing parameters and voltage levels for compatibility. Check for equivalent automotive qualification status. Consult Micron's product catalog for updated alternatives if this part is discontinued.

Memory IC FAQ

What is the refresh rate for the AIT option?

The Automotive Industrial Temperature (AIT) option requires a 64ms, 8192-cycle refresh rate.

Does this device support self-refresh mode?

Self-refresh is not available on Automotive Temperature (AAT) devices. Standard versions may support it depending on the specific configuration.

How many data strobes are present in the x16 configuration?

The x16 configuration has two bidirectional data strobes (DQS), one for each byte.
