Electric Feature

The I2C interface has the following features:

1. The two-wire bus is used for the communication between ICs.

2. It supports any external equipment of any manufacturing technology (1.8V).

3. It supports the external functions, such as the image sensor, micro controller,

FM radio chip, LCD chip, audio DAC and keyboard interface.

The I2C interface has two working modes with different transmission ratios:
standard mode with a speed as high as 100kbps; high-speed mode with a speed as
high as 400kbps. Figure 3-6 is the I2C reference circuit design diagram.
