This slide shows a typical application for this Bridge. There are three I2C devices connect to the Bridge’s I2C bus: an EEPROM, a LED dimmer and a GPIO expander. The SPI-based host sends and receives data from any of these three devices by sending the physical address of the particular device along with the data (commands) to the Bridge. The Bridge will then translate these data (commands) to I2C electrical signals on the I2C bus. It then sends the host’s data (commands) to the correct device. This device supports multi-master I²C networks.
