I3C (bus)
I3C, also known as SenseWire, is a specification to enable communication between microchips by defining the electrical connection between the chips and signaling patterns to be used. Short for Improved Inter-Integrated Circuit, the standard defines the electrical connection between the chips to be a two wire, shared (multidrop), serial data bus, one wire (SCL) being used as a clock to define the sampling times, the other wire (SDA) being used as a data line whose voltage can be sampled.
