Controller offers easy route to
embedding Ethernet
The CP220x is billed as the industry's smallest and highest performance single-chip Ethernet controller addressing today's most widely deployed local area network technology.
Silicon Laboratories has announced the CP220x, the industry's smallest and highest performance single-chip Ethernet controller addressing today's most widely deployed local area network (LAN) technology By reducing the amount of board space required by up to 90% and minimising the overall system cost and complexity, the CP220x enables designers to easily add embedded Ethernet connectivity to a broad range of products including POS terminals, access control devices, security panels, VoIP adapters, vending machines, appliances, industrial monitoring and control devices or any other product that is in proximity to an Ethernet network

MCU incorporates high-resolution conversion
The C8051F350 is precision mixed-signal microcontroller that integrates an eight-channel, 24bit ADC with a high-speed 8051-compatible CPU.
Available in a small 5 x 5mm package, the CP220x includes an integrated IEEE802.3-compliant 10Base-T Ethernet MAC and PHY and 8Kbyte of onboard Flash memory that is factory preprogrammed with a unique 48bit MAC address to eliminate the serialisation step from the product manufacturing process of most embedded systems.
The onboard Flash can be used to store user constants and web server content or as general-purpose nonvolatile memory.
By implementing a high-performance parallel external memory interface with an operating speed of up to 30Mbit/s, the CP220x allows the companion MCU to execute stack or other code much more efficiently since less time is spent in communication.

Analogue front end supports ADSL2+ datarates
The Si3110 is heralded as the industry's smallest, high-performance, integrated analogue front end (AFE) for ADSL and ADSL2+ applications.
The new device is capable of operating from -40 to +85C while consuming only 70mA, or as little as one-third the current of competing devices.
The CP220x also supports auto-negotiation, which often is the only mechanism available to the user to inform the network of the controller's complete Ethernet capabilities.
Without this mechanism or user control of the switch, the relevant network segment will default to its lowest common capability resulting in a lower bandwidth communication solution.
"Due to the ease-of-use and low maintenance costs, Ethernet has become broadly used in applications as varied as facilities management and utility and vending machine monitoring", said Derrell Coker, Vice President of Silicon Laboratories.
"As the industry's smallest, highest performance embedded Ethernet controller, the new CP220x simplifies our customers' task of adding embedded Ethernet capability to any product that has access to an Ethernet network".
Silicon Laboratories offers an Ethernet development kit that provides all of the hardware and software necessary to develop real-world embedded Ethernet solutions with the CP220x.
Included in the kit is a C8051F120 MCU target board, a CP2200-based Ethernet development board, a USB debug adapter and all necessary cables to debug the MCU and connect it to an Ethernet network.
The CMX Micronet TCP/IP protocol stack, which was developed specifically for embedded processors, is included in an easy-to-use library format.
A TCP/IP configuration wizard is provided to generate a highly customised library optimised for user-selected protocols.
This wizard generates both the framework code required to use the library and a project file that can be managed within the Silicon Laboratories integrated development environment (IDE).
The Ethernet Development Kit is available for $199.
The CP220x is available in a 5 x 5mm 28-pin quad flat no-lead (QFN) package or a 48-pin thin quad flat package (TQFP).
Pricing for the CP220x family begins at $3.32 in quantities of 10,000.
Samples are available now with production quantities available beginning in Q2 2006.
