2.  CP2201EK Overview

The purpose of the CP2201EK is to provide a way to easily evaluate Silicon Laboratories Ethernet Solutions and
view some of the applications made possible by the CP2200/1. To develop embedded applications using the
CP2200/1, we offer a complete Embedded Ethernet Development Kit (Ethernet-DK). The Embedded Ethernet
Development Kit contains a TCP/IP Configuration Wizard that automatically generates code to perform many of the
functions in the CP2201EK. Numerous code and application examples are also provided in the development kit.
The CP2201EK is a fully contained evaluation board. The main system controller, which runs the TCP/IP Stack and
performs other system tasks, is a 50 MIPS Silicon Laboratories C8051F340. The Ethernet controller providing
network connectivity is the Silicon Laboratories CP2201—the industry’s smallest Ethernet controller. The third
major component on the board is the Ethernet connector (RJ-45) with integrated magnetics and LEDs. 
On the software side, the C8051F340 is running the CMX Micronet Web Server. The embedded web server has
web pages for displaying temperature and light sensor data, controlling the yellow LED state, sending an e-mail,
remotely updating firmware, and displaying images and CP2201 Key Features. The embedded system can also be
accessed through a command line Telnet interface.
Figure 1 shows the CP2201EB and identifies its various components.
