Title: What is the AT18 on I2C4 Bus? [Print This Page] Author: adriangin Time: 3/9/2018 13:04 Title: What is the AT18 on I2C4 Bus? I have a look at the DTS, and I2C4 describes 3 devices.
On Schematic: AT18 does not have address on the I2C Bus, but it has a reference to 'Encryption'.
AT18 is a 8pin device according to schematic and PCB. It is also NC which mean it does not loaded or populated on the PCB.
My question is: What is this Mysterious AT18 used for?
Thank you.

As the name suggests, it is reserved for some clients to support encryption.
