【Abstract】 The SF0020 is an 8-bit embedded network microcontroller, with 10/100M bps EthernetMAC. Its IEEE 802.3 MII interface can directly connect to physics layer chip DM9161 and enable theSF0020 to access and communicate over the Ethernet. In this article, the features of SF0020 andDM9161 and how to connect SF0020 to DM9161 are mainly presented. The application program designbased on TCP/IP of the system is presented too.更多还原
