Abstract
The present invention provides an I2C interface system based on an I2C slave device, which comprises an I2C Master Controller, an I2C Slave Device, a first functional module, and a second functional module; the I2C Master Controller is connected to the I2C Slave Device via an I2C clock line and an I2C data line; the I2C Slave Device is connected to the first functional module and the second functional module. The present invention realizes supporting two modes of I2C data transmission (command packet transmission and operational data byte transmission) using only one I2C slave device, saves interface signals, and solves the problem of insufficient chip pins in small-package integrated circuits.
