MIPI Specification for I3C Version 1.0

Improved Inter-Integrated Circuit, v1.0, 23 December 2016
The proliferation of sensors in mobile wireless and mobile-influenced products has created significant design
challenges. Because there are no consistent methods for interfacing physical sensors, Device and platform
designers are faced with digital interface fragmentation that includes I2C, SPI, and UART among others.
In addition to the main interface other signals may be needed, such as dedicated interrupts, chip select signals, and enable and sleep signals. This increases the required number of Host GPIOs, and that in turn drives up system cost with more Host package pins and more PCB layers.
As time passes and the number of sensors increases, this situation is becoming increasingly difficult to
support and manage.
The MIPI I3C interface has been developed to ease sensor system design architectures in mobile wireless
products by providing a fast, low cost, low power, two-wire digital interface for sensors.
