Abstract
Embedded systems are applied widely in many fields,except for net connecting.It is necessary for net interface module to satisfy these demonds.The core chip Ethernet controller CS8900A and its work mechanism are introduced. Transferring and Receiving of Ethernet frame by configuring CS8900A's internal registers are analyzed in detail. Scheme of combining efficient hi-speed MCU C8051F005, CS8900A and MAX232 is adopted.Interface circuit and system controlling software are studied.Embedded system Interface module based on ethernet is designed successfully.
