Memory IC Procurement Notes

Verify the specific suffix ET against official datasheets to confirm the commercial temperature grade (0°C to 70°C). Ensure the TSOP II package dimensions match the target PCB footprint. Confirm RoHS3 compliance status through current manufacturer documentation before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when a 64Mbit SDRAM solution with LVTTL compatibility is required. Compare the commercial temperature range against industrial alternatives if wider thermal tolerance is needed. Verify that the 54-TSOP package size fits the available board space constraints.

Memory IC Part Context

This part belongs to the NDS66P series of synchronous dynamic random-access memory devices. It shares core electrical characteristics with variants like the NDS66PT5-16IT, differing primarily in packaging or temperature rating. The series targets applications needing moderate-speed volatile memory in compact surface-mount formats.

Memory IC Replacement Considerations

NDS66PT5-16IT offers identical electrical performance but may differ in temperature rating or package type. Cross-reference pinouts and timing parameters with official substitution guides to ensure functional equivalence.
