The I2C-Bus is a 2-wire bidirectional synchronous serial bus that allows computer to connect to ICs,which is initially developed by Philips corporation.In Linux kernel,a special I2C driver architecture was developed to support I2C Bus peripheral.Based on the principles of I2C Bus controller in the MPC8250 processor and the Linux I2C driver architecture,for MPC8250′s I2C Bus as an example, the design method about EEPROM driver based upon I2C Bus is present.
