Design and Implementation for Interfacing Two Integrated Device Using I2C Bus

Pankaj Kumar Mehto, Pragya Mishra , Sonu Lal

In this paper we focus on the design of I2C bus controller and the interface between the two integrated devices i.e. microcontroller and EEPROM like as a master controller and a slave for serial communication in embedded system. The components of the I2C bus controller is consist of only a bidirectional two wire and standard protocol which communicate between two integrated circuit or device. First one is serial data (SDA) line and second is serial clock (SCL) line. The I2C protocol was given by Philips Semiconductors for faster devices to communicate with slower devices and each other without data loss. The complete module is designed in VHDL and simulated in ModelSIM. The design is also synthesized in Xilinx XST 14.1.
