This paper mainly introduces the application of TEF6606 chip in car radio. According to the characteristics of automotive power supply, a reasonable circuit is designed, so the lower power consumption can be achieved in power-saving mode. The MCU control the corresponding registers of TEF6606 chip by the I2C bus to implement the digital tuned stereo radio. And in order to meet the different requirements, the diversification of tuning function , such as audio-search and scampering modes, can be realized by programming.
