The TL16C552 is an asynchronous communication chip produced by TI Company. The chip can be used to achieve high-speed serial communication and printer port expansion when the real-time requirements of the communication system are high, so as to enhance the controllability of the communication interface of the system. In this paper, the performance of the TL16C552 and the registers related to the communication are introduced. The hardware application circuit of the TL16C552 in the TMS320VC33 and the PC communication system of the DSP device is given and the software programming of the TL16C552 is initialized by the TMS320VC33
