Techopedia Explains Inter-IC (I2C)

Developed by Phillip Semiconductors in 1980, the I2C was initially designed to lessen costs by streamlining massive wiring systems with an easier interface for connecting a central processing unit (CPU) to peripheral chips in a television. It originally had a battery-controlled interface but later utilized an internal bus system.
