NXP I2C-bus solutions
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.**
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).
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.**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.
