Rev. 1.0

1. System Overview

The CP2200/1 is a single-chip Ethernet controller containing an integrated IEEE 802.3 Ethernet Media Access

Controller (MAC), 10BASE-T Physical Layer (PHY), and 8 kB Non-Volatile Flash Memory available in a compact

5 x 5 mm QFN-28 package (sometimes called “MLF” or “MLP”) and a 48-pin TQFP package. The CP2200/1 can

add Ethernet connectivity to any microcontroller or host processor with 11 or more Port I/O pins. The 8-bit parallel

interface bus supports both Intel and Motorola bus formats in multiplexed and non-multiplexed mode. The data

transfer rate in non-multiplexed mode can exceed 30 Mbps.

The on-chip Flash memory may be used to store user constants, web server content, or as general purpose non-

volatile memory. The Flash is factory preprogrammed with a unique 48-bit MAC address stored in the last six

memory locations. Having a unique MAC address stored in the CP2200/1 often removes the serialization step from

the product manufacturing process of most embedded systems.

The CP2200/1 has four power modes with varying levels of functionality that allow the host processor to manage

the overall system power consumption. The optional interrupt pin also allows the host to enter a “sleep” mode and

awaken when a packet is received or when the CP2200/1 is plugged into a network. Auto-negotiation allows the

device to automatically detect the most efficient duplex mode (half/full duplex) supported by the network.

The Ethernet Development Kit (Ethernet-DK) bundles a C8051F120 MCU Target Board, CP2200 Ethernet

Development Board (AB4), the Silicon Laboratories IDE, all necessary debug hardware, and a TCP/IP

Configuration Wizard. The Ethernet Development Kit includes all hardware, software, and examples necessary to

design an embedded system using the CP2200. The CP2200 Ethernet Development Board is also compatible with

the C8051F020TB and C8051F340TB. Individual target boards may be purchased online by visiting
