Memory IC Procurement Notes

Verify the specific suffix designation against current manufacturer documentation, as legacy components may have multiple revisions or manufacturing sources. Confirm end-of-life status and availability through authorized distributors, as supply chains for older SDRAM generations can be restricted. Ensure compatibility with existing PCB footprints and signal integrity requirements before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when a 512-Mbit capacity with a 16-bit interface is required for industrial applications. The -7TIN suffix indicates commercial speed grades and industrial temperature ratings suitable for harsh environments. Compare against alternative pin-compatible parts if lead times are critical, ensuring voltage levels and timing parameters match the system design constraints.

Memory IC Part Context

This part belongs to the AS4C32M16SA series of SDRAMs. Alliance Memory provides these devices as long-term solutions for legacy designs, often collaborating with other manufacturers like Micron for production continuity.
