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.

It's already a 10+ year old.design, why did you pick it over newer alternatives?

Availablabilty can be as deep as your own stockroom.
