I3C (bus)

I3C is an emerging industry standard for multidrop serial data buses. I3C was developed as a collaborative effort between electronics and computer related companies under auspices of the Mobile Industry Processor Interface Alliance. I3C is an evolution of I²C, a de facto standard two-pin serial bus widely used for low-speed peripherals and sensors in computer systems. I3C adds a significant number of system interface features while retaining backward compatibility with existing I²C slave devices while native I3C devices support higher data rates, similar to Serial Peripheral Interface (SPI). Like I²C, I3C uses two signal pins named SDA and SCL. One or more master devices can be connected to one or more slaves over the bus.
