MIPI I3C

MIPI I3C is a serial communication interface specification that improves upon the features, performance, and power use of I²C, while maintaining backward compatibility for most devices.

MIPI I3C carries the advantages of I²C in simplicity, low pin count, easy board design, and multi-drop (vs. point-to-point), but provides the higher data rates, simpler pads, and lower power of SPI. MIPI I3C then adds higher throughput for a given frequency, In-Band Interrupts (from Target to Controller), Dynamic Addressing, advanced power management, and Hot-Join.

MIPI I3C was initially intended for mobile applications as a single interface that can be used for all digitally interfaced sensors. However, it is now intended for all mid-speed embedded and deeply-embedded applications across sensors, actuators, power regulators, MCUs, FPGAs, etc. The interface is also useful for other applications, as it offers high-speed data transfer at very low power levels while allowing multi-drop, which is highly desirable for any embedded system.

DDR5 also uses MIPI I3C as one of the core technologies for DDR5 SPD. After using MIPI I3C instead of I²C, the bit rate can be increased by 12.5x to 125x depending on the actual build condition.

Application: I3C is an extension of I²C, the speed is about 12.5MHz / Signal: SCK, SDA / Voltage: 3.3~1.2V
