Study of ethernet interface unit base on RTL8019AS

Qing Deng

Abstract

Base on TCP/IP protocol, this paper introduced a kind of realization method of MCU connecting to Ethernet, the RTL8019AS chip interior configuration is analyzed which made by REALTEK company. Refering to the characteristics and the operation principle of RTL8019AS, the concrete scheme of hardware design . realization of program and program diagram is given. This unit can be use for interface among MCU's or between monitor system and MCU. The design uses TCP/IP protocol and limited buffer to share MCU on network.
