WebbI2C (sometimes abbreviated as I²C or IIC) stands for the inter-integrated circuit. It was developed by Phillips in 1982 for many of its chips. Originally, I2C allowed for only 100kHz communications to be used. Only 7-bit addresses were provided, and thus only 112 devices could be connected on the bus. Ten years later, 400kHz fast-mode was added.
