AN50987 gives an overview of the I²C standard and explains how a PSoC^® 1 device handles I²C communications. After reading this application note, you should have an understanding of how I²C works, how to implement it in PSoC 1, and how to choose the correct user module for a design. Example projects demonstrate how to configure PSoC 1 as an I²C master/slave to communicate with other I²C devices on the bus.

Inter-integrated circuit (IIC or I²C) is a common chip-tochip serial communications standard developed by the Philips semiconductor division (now NXP). I²C provides a simple way for ICs to communicate on the same printed circuit board (PCB). I²C consists of a simple physical layer that requires only two pins and minimal external components. One advantage of I²C over a communication standard such as SPI is that it has a built-in communication protocol that allows easy, error-free communication between devices.

The following video explains the basics of I²C communication protocol.
