Start with the requirement
Maintain an approved manufacturer list with full ordering codes, datasheet revisions, qualification records and change-notification ownership.
Technical context
Winbond distinguishes mass production, not recommended for new design and end-of-life statuses in its product directory. Availability and lifecycle are different questions.
Procurement review
Review PCNs and discontinuation notices periodically. Plan last-time buys from forecasted demand and storage constraints, and develop a separate qualification schedule for alternatives.
