Inter-Integrated Circuit (I2C)

The Inter-Integrated Circuit by Philips is a popular interconnect (typically on-board) used on embedded processors as well as modern computers consisting of 2-wires (other than ground, power, and optional interrupts):

  • SCL - clock
  • SDA - data

An I2C bus may be multi-master and support interrupts from the device to host controller.
