products.
What products are affected and what is the notification
strategy? Microchip has identified the parts affected and is
implementing a notification strategy with a three phase
Product/Process Change Notice (PCN) approach.
Phase 1: Microchip issued an initial PCN (PCN#) on
September 9, 2016. The PCN number is JAON-
01RSNA976 and includes the following information:
a. Qualification plan.
b. Anticipated quarter and year for availability of the
qualification report.
c. Affected parts list
Phase 2: Microchip will issue an intermediate PCN after
qualification has completed. Included in this PCN is:
a. Qualification report
b. Complete list of Catalog Part Numbers (CPN) for
the qualified S1 process technology.
The objective of this PCN is to notify customers that the
S1 process technology has completed qualification and
provide the report.
