I3C® - Improved Inter-Integrated Circuit Module

The Improved Inter-Integrated Circuit (I3C) is a multi-Controller serial data communication interface which builds upon the traditional Inter-Integrated Circuit (I2C) interface. Similar to I2C, devices on the I3C bus communicate in a Controller/Target environment where either the Controller or the Target device can initiate the communication. The I3C interface is developed by the MIPI® Alliance and provides a fast, low-cost, low-power managed two-wire digital interface to improve sensor and device integration. The I3C interface is also backward compatible with the I2C standard.

The I3C module on this device supports Target functionality only, with no Controller capabilities. Figure 1 shows a block diagram of the I3C Target module interface.
