Procurement Notes

This product is officially listed as no longer manufactured by Nuvoton Technology Corporation. Procurement efforts should focus on verifying the authenticity and condition of available stock from authorized distributors or secondary market suppliers. Buyers must confirm RoHS compliance status and check for any applicable tariff regulations when shipping to specific regions, such as the United States, prior to finalizing orders.

Selection Notes

Engineers selecting this component should note its discontinued status, which may impact long-term supply chain stability. Alternative solutions within the same family or newer generations from Nuvoton should be evaluated for compatibility with existing DDR voltage requirements. Designers must ensure that the TO-252-5 package footprint matches their PCB layout constraints and verify thermal performance specifications against their system's heat dissipation capabilities.
