I2C Bus

  • Warren W. Gay


The I2C bus, also known as the two-wire interface (TWI), was developed by Philips circa 1982 to allow communication with lower-speed peripherals.49 It was also economical because it required only two wires (excluding ground and power connections). Since then, other standards have been devised, building upon this framework, such as the SMBus. However, the original I2C bus remains popular as a simple, cost-effective way to connect peripherals.
