Abstract: CP2200 is a network interface chip. Its small size, simple external circuit, low cost makes it easier to design with a microcontroller interface. Based on TCP/IP protocol analysis, a concise and practical TCP/IP protocol subset with the characteristics of embedded systems and CP2200 chip is selected. This paper describes the implementation of the protocols. It provides a relatively simple and practical idea for the development of embedded network system.
