LSM6DS33 longevity

Hello,

We're using the LSM6DS33 accelerometer/gyrometer in a product, which is expected to be continuously manufactured for ~5 years. 

I'm slightly worried about its longevity. I know that nowadays it is listed as Active, and also that it is not in any longevity program.

Is it expected to be classified as NRND soon? Can I use it in this application without worries or should I be prepared for future changes since the beginning?

Thanks,

[Bogdan Golab]

The 10 years longevity commitment includes the period of notification as set forth in the standard STMicroelectronics end-of-life notification policy (PTN).

In case of significant volume decrease, technology or manufacturing changes, a switch to a comparable product, another technology or a different manufacturing facility could be decided by  STMicroelectronics who will notify customers using the standard STMicroelectronics product/process change policy (PCN).

Hello Luis,

there should be no problem having LSM6DS33 in production for 5 years, but I would suggest to use LSM6DS3 which is software compatible and more likely to stay in production for long time.
