The Lifecycle of the STM32L151

How about the lifecycle of the STM32L151? We are designing a new project. Is it available in another 15 years?

Some STM32L151 chips are already NRND. If it's one of those, no. The ones that are still active have a 10 year product commitment. Typically, this gets pushed out yearly but there's no guarantees past 10 years. At the very least, you'll get a 9-year heads up that the chip may be going away if you check the list yearly.

Availablabilty can be as deep as your own stockroom.

As noted in that article, you need to give the full part number for a specific answer.

When you go to the Product Page for the specific part, you will see the status, and lifetime promise ("longevity"); eg,
