1. Overview
The Embedded Ethernet Development Kit (Ethernet-DK) provides all the hardware and software required to
develop real-world embedded Ethernet applications using the industry proven CMX Micronet™ protocol stack and
high-performance Silicon Laboratories microcontrollers. The TCP/IP protocol stack is developed specifically for
embedded processors and is freely distributed in an easy-to-use library. A TCP/IP Configuration Wizard is provided
to generate a highly customized library optimized for user selected protocols. It also generates the framework code
required to use the library and a project file that can be managed in the Silicon Laboratories Integrated
Development Environment (IDE). Additional information about the TCP/IP library and Configuration Wizard,
including a detailed API description, can be found in application note “AN237: TCP/IP Library Programmer’s
Guide”.
The Embedded Ethernet Development Kit hardware includes a C8051F120 Target Board, AB4 Ethernet
Development Board, USB Debug Adapter, and all necessary cables to debug the MCU and connect it to an
Ethernet network. The C8051F120 Target Board features the 100 MIPS, 128 kB Flash, 8 kB RAM, 8051-based
C8051F120 MCU. The MCU network interface provided by the AB4 board consists of the CP2200 Ethernet
controller and an RJ-45 connector with integrated magnetics and LEDs. The TCP/IP Library includes a built-in
driver for the CP2200 and has a custom driver interface with auto-generated templates to allow drivers for any
Ethernet controller to be written.
The Silicon Labs IDE supports full-speed, non-intrusive MCU debugging and is bundled with an evaluation version
of the Keil C51 Toolchain allowing immediate application code evaluation in C. Projects with up to 4 kB of object
code and unlimited library code can be developed using the included toolset. Numerous application code examples
are included in the development kit and a walkthrough of an embedded web server demo is included in Section 6
on page 9.
