MIPI I3C® is a scalable, medium-speed, utility and control bus interface for connecting peripherals to an application processor, streamlining integration and improving cost efficiencies. It gives developers unprecedented opportunities to craft innovative designs for any mobile product—from smartphones, to wearables, to systems in automobiles.
MIPI I3C incorporates key attributes of the traditional I2C and SPI interfaces to provide a unified, high-performing, very-low-power solution and delivers a robust, flexible upgrade path to I3C for I2C and SPI implementers. While I3C v1.0 delivered new capabilities to integrate mechanical, motion, biometric, environmental and any other type of sensor, MIPI I3C v1.1 (now v1.1.1) built on that capability by adding new features for peripheral command, control and communication to a host processor over a short distance and system manageability.
MIPI I3C is developed by the MIPI Alliance I3C Working Group.
