Hi, what is the use of this piece and what is it used for? Is it considered an electrical circuit? Tell me a little about it, I will buy it. My warmest regards to you.
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

Hi I read the article about the specifications and I3C technology. It is really an excellent and advanced piece. I will buy it from DigiKey. It is a wonderful company. Thank you for the wonderful information. I will buy more electrical circuits from DigiKey. There are more advanced electronic parts. My warm greetings to you and to the forum manager, the wonderful engineer. Thank you.
Hi @sikwal
ST has a good introduction here:
Introduction to I3C for STM32 MCUs: https://www.st.com/content/ccc/resource/technical/document/application_note/group2/cc/0b/d3/5d/4b/25/49/b2/DM00921273/files/DM00921273.pdf/jcr:content/translations/en.DM00921273.pdf

Hi, thank you, dear engineer. My warm regards to you, sikwal.
Hi, please tell me more about the new technology, which is I3C, as I have read many articles about its uses, as it is used in phones, medical devices, smart watches, and many others, and how it has evolved from I2C to I3C I, which is faster in transferring data.
There is a good write-up here, they should have a native language page for you, I3C (bus) - Wikipedia
Even more complex: https://picture.iczhiku.com/resource/eetop/sYKeRrsPKZzJGbxc.pdf
