C (Inter-Integrated Circuit)
I
2
C is a simple bi-directional two-wire bus for efficient inter-integrated circuit control. All I
2
C -bus
compatible devices incorporate an on-chip interface that allows them to communicate directly with
each other via the I
2
C-bus. This solves the many interfacing problems encountered when designing
digital control circuits. These I
2
C 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.
