I²C-bus: The serial revolution

By replacing complex parallel interfaces with a straightforward yet powerful serial

structure, the I²C-bus revolutionized chip-to-chip communications.

SDA

SCL

Invented by NXP (Philips) more than 30 years ago, the I²C-bus uses a simple two-wire

format to carry data one bit at a time. It performs inter-chip addressing, selection,

control, and data transfer. Speeds are up to 400 kHz (Fast-mode), 1 MHz (Fast-mode

Plus), 3.4 MHz (High Speed-mode), or 5 MHz (Ultra Fast-mode).

Parallel Interface

I²C Serial Interface

The I²C-bus shrinks the IC footprint and leads to lower IC costs. Plus, since far fewer

copper traces are needed, it enables a smaller PCB, reduces design complexity, and

lowers system cost.

as assigned

I²C-bus devices are available in a wide range of functions. Each slave device has its own I²C-bus address, selectable using

address pins set high (1) or low (0). Information is transmitted byte by byte, and each byte is acknowledged by the receiver.

There can be multiple devices on the same bus, and more than one IC can act as master. The master role is typically played by a

microcontroller.
