At the same time, whether at home, office or elsewhere, you can easily connect to the Internet. The convenience of Internet access is greatly increased, and costs are getting lower and lower, if they can achieve Each device access Internet , can be convenient, inexpensive way to transmit the information to almost any one place, globalization of information. Therefore, in addition to the traditional portable, low power consumption, such as performance, network access ability which is increasingly becoming the focus of embedded system. This design introduces a design based on MCU Ethernet access, Ethernet access to the smallest single chip system structure, and the Ethernet controller ENC28J60 works. Mainly proposed to streamline the TCP / IP protocol stack embedded microcontroller system is achieved through the ENC28J60 data in the Ethernet data transmission. Given system hardware design schematics and the realization of TCP / IP protocol conversion, and program code, hardware and software designed to make the system are described, and gives the design results. The results show that the software embedded TCP / IP protocol of the SCM system with low cost, less hardware, transmission speed, ease of use
