Procurement Notes

Verify the specific suffix 'TR' against official Nuvoton documentation to confirm tape-and-reel packaging status. Ensure the part number matches the exact electrical specifications required for your DDR SDRAM application. Cross-reference with Winbond datasheets if necessary, as manufacturing rights may have transferred. Confirm lead-free and RoHS compliance details in the final procurement order.

Selection Notes

Select this component for designs requiring a linear bus termination solution for DDR memory interfaces. It is suitable for systems utilizing SSTL-2 or SSTL-3 standards. Consider its integration of power MOSFETs when evaluating board space constraints. Verify compatibility with +3.3V and +2.5V control power domains before finalizing the schematic.
