摘　　要：讨论了新型以太网交换控制芯片RTL8305SB在嵌入式系统中的应用,提出了一种将其用于嵌入式智能网桥—CAN-ETHERNE的互连方案,详细阐述了MII总线的配置方法以及RTL8305SB与光纤收发器的连接方案;提出了有实际应用价值的RTL8305SB 2.5V电源生成方法,在实际应用中大大提高了RTL8305SB的稳定性。通过自制PCB版图,在开发板上自编程序,实现了多路CAN总线与以太网信息的转发,达到了预期的设计效果。The application of a new exchangeable and controllable Ethernet chip RTL8305SB in the embedded system is discussed in the paper. The interlink plan of embedded intelligent network-bridge （CAN-ETHERNE） by employing RTL8305SB is proposed. The configuration method of MII and the interlink plan between RTL8305SB and op- tic fiber transceiver are elaborated. A new method of creating RTL8305SB 2, 5V power which can greatly improve the stability of RTL8305SB is given. Through self-made PCB board, the program is self-coded in the development board, the transmission between many CAN buses and Ethernet is realized, and the anticipated design purpose is achieved.
