In consumer electronics, telecommunications and industrial electronics, there are often many similarities between seemingly unrelated designs. For example,
nearly every system includes:
Some intelligent control, usually a single-chip microcontroller
General-purpose circuits like LCD drivers, remote I/O ports, RAM, EEPROM, or data converters
Application-oriented circuits such as digital tuning and signal processing circuits for radio and video systems, or DTMF generators for telephones with tone dialling.
To exploit these similarities to the benefit of both systems designers and equipment manufacturers, as well as to maximize hardware efficiency and circuit simplicity, Philips developed a simple bi-directional 2-wire bus for efficient
inter-IC control. This bus is called the Inter IC or I2C-bus.
