The basic idea of the project is to provide internet interface for embedded systems. The goal of this design project is to create a device that will enable other devices to communicate over the Internet. This is accomplished by putting together a network such that it is low cost, small in size, and does not consume too much processor resources. The design chosen for this project is a User Datagram Protocol over the Internet Protocol over Ethernet (UDP/IP/Ethernet) implementation on an Intel 8051 microcontroller.
For demonstration purposes, a temperature sensor device is added. The temperature sensor sends the sensed temperature to the Internet Interface. The Internet Interface is connected through Ethernet on a local area network. It creates UDP packets and sends it across the Internet. The destination for the packet is the web server, and on the web server is a listener program. The program receives the UDP packet and puts the temperature data onto a web page. The demonstration shows that a device (i.e. a temperature sensor) can communicate over the Internet, and it can be monitored remotely.
Referening books on emebedded ethernet gives information about the cirrus CS8900A-CQ 8/16 bit mircocontroller NIC which could be easily programmed.

Availability of Embedded Ethernet Module:

In this regard I would like to know, if there is any 10Base-T Embedded Ethernet module (preferrably with cirrus CS8900A-CQ 8/16 bit ethernet chip) which would ease my design complexity by providing the direct interface between microcontroller bus and the Ethernet port (RJ-45).

is there a way i configure the same using RTL8019AS ???

can some one help me out???
