I2C

Introduction
As the inventor and world leader in I2C devices, we have a vast portfolio of products with I2C interfaces. We have dedicated products used to expand and interconnect I2C-bus systems including general purpose I/O expanders, repeaters/hubs/extenders, and LED controllers. Our I2C logic products are ideal for many systems using SMBus, AdvancedTCA (ATCA) IPMI, and PMBus.

Applications
The I2C-bus is used in virtually every application. I2C I/O expanders are used for keyboard/pad input or for controlling LED status lights. Adding UART/IrDA functionality to a cellular phone, for example, is simple via the I2C bus with a choice of bridge ICs.
For numerous cellular handsets, LED blinkers and dimmers can control keypad, fun lighting, and other status LEDs. These ICs can also be used for more advanced status or illumination control while offloading the host processor in LCD displays. LCD segment drivers or LCD matrix drivers with an I2C interface are ideal for displays in cordless telephone handsets.
I2C serial EEPROMs can be used to store preset information in an MP3 player or large LCD display, where PAL or NTSC settings during manufacture are set using I2C DIP switches. For environmental sensing, I2C temperature sensors are used to monitor local temperatures. This is particularly important in wireless basestations, where I2C repeaters/hubs/extenders are also used to isolate capacitance from the backplane.
Below are just some of the applications where you can use the different categories of I2C-bus devices.
