Product/Process Change Notifications

Altera maintains an established procedure to comprehensively assess product/process changes, determining their impact on form, fit, and function, and ensuring no adverse effect on product quality and reliability.

This customer notification procedure adheres to JEDEC J-STD-046 (Customer Notification Standard for Product/Process Changes by Electronic Product Suppliers) and J-STD-048 (Notification Standard for Product Discontinuance).

There are three (3) types of notifications:

Customer	Notification Type	Description
PCN	Process Change Notification	This notice advises customers of a product or process change, references J-STD-046, and follows a 90-day minimum notification period. Important Note: Absence of customer feedback or response after the minimum notification period will be considered acceptance of the change
ADV	Customer Advisory	This is an information-only notification provided for minor changes (e.g., label content or marking adjustments). It is also used when customer approval is not required for implementation, as with datasheet, user guide, or errata/known issues list updates. The usual notification period is 30 days or fewer.
PDN	Product Discontinuance Notice	This notification informs customers of a product's end-of-life or discontinuance. The standard Last Time Buy (LTB) period is 6 months, and the Last Time Ship (LTS) period is 12 months, both calculated from the notification date.
