The MIPI I3C host interface is an evolutionary standard that improves upon the features of I2C, while maintaining backward compatibility. This standard offers a flexible multi-drop interface between the host processor and peripheral sensors to support the growing usage of sensors in embedded systems.
The main purpose of MIPI I3C is threefold:
To standardize sensor communication
Reduce the number of physical pins used in sensor system integration and
Support low-power, high-speed and other critical features that are currently covered by I2C and SPI.
