Hello @sikwal
The short answer, the ST1VAFE3BC is a biosensor and accelerometer with Ai and antialiasing to be used in wearable and portable devices for activity and health tracking purposes.
I did take a look at this chip on STMicroelectronics site, they already have a lot of information about this chip, and it does a much better job of explaining what it is, and how it can be used then what I would be able to.

One interesting thing for me at least is this is the first chip I have come across that has I3C output protocol for it. We do have an article on our TechForum about the I3C communication protocol and I have included that as well in case you want to know more
