All I2C -bus compatible devices incorporate an on-chip interface that allows them to communicate directly with each other via the I2C-bus. This solves the many interfacing problems encountered when designing digital control circuits. These I2C devices perform communication functions between intelligent control devices (e.g., microcontrollers), general-purpose circuits (e.g., LCD drivers, remote I/O ports, memories), and application-oriented circuits.
