I3C - Function Controller

Overview

The I3c protocol, short for " Improved Inter - Integrated Circuit," is a communication protocol designed to improve upon the widely - used I2C protocol. It was developed by the MIPI Alliance, a global organization that aims to develop interface specifications for mobile devices.

The I3c protocol includes several key features that make it an improvement over I2C. For example, it supports higher data speed, around 12.5MHz, which allows for faster communication between devices. It also includes dynamic address assignment, which allows devices to be added or removed from the bus without disrupting the communication of other devices

Another feature of I3c is its support for both Legacy I2C slaves and I3C slave devices, which makes it compatible with a wide range of existing hardware. Additionally, it includes support for advanced features such as sensor fusion, which allows multiple sensors to be combined to provide more accurate data.In addition to the features mentioned earlier, the I3c protocol also includes support for low - power modes, which can help conserve battery life in mobile devices. It also includes enhanced error detection and correction capabilities, which can help ensure the reliability of data transmission.
