Its highly-integrated design eliminates the need for costly external components required by other Ethernet controllers. The CS8900A includes on-chip RAM, 10BASE-T transmit and receive filters, and a direct Bus interface with 24 mA Drivers. In addition to high integration, the CS8900A offers a broad range of performance features and configuration options. Its unique PacketPage architec- ture automatically adapts to changing network traffic patterns and available system resources. The result is increased system efficiency. The CS8900A is available in a 100-pin TQFP package ideally suited for small form-factor, cost-sensitive Ethernet applications. With the CS8900A, system engineers can design a complete Ethernet circuit that occupies less than 1.5 square inches (10 sq. cm) of board space.

Key Benefits Low Power and Low Noise Very Low Cost For low power needs, the CS8900A offers three power-down options: Hardware Standby, Hardware Suspend, and Software Suspend. In Standby mode, the chip is powered down with the exception of the 10BASE-T receiver, which is enabled to listen for link activity. In either Hardware or Software Suspend mode, the receiver is disabled and power consumption drops to the micro-ampere range. The CS8900A is designed to provide the lowestcost Ethernet solution available for embedded applications, portable motherboards, and adapter cards. Cost-saving features include: • • • • • • Integrated RAM eliminates the need for expensive external memory chips. On-chip 10BASE-T filters allow designers to use simple isolation transformers instead of more costly filter/transformer packages. The serial EEPROM port, used for configuration and initialization, eliminates the need for expensive switches and jumpers. The CS8900A is designed to be used on a 2-layer circuit board instead of a more expensive multilayer board. The 8900A-based solution offers the smallest footprint available, saving valuable printed circuit board area. A set of certified software drivers is available at no charge, eliminating the need for costly software development. High Performance The CS8900A is a full 16-bit Ethernet controller designed to provide optimal system performance by minimizing time on the bus and CPU overhead per frame. It offers equal or superior performance for less money when compared to other Ethernet controllers. The CS8900A’s PacketPage architecture allows software to select whichever access method is best suited to each particular CPU/bus configuration. When compared to older I/O-space designs, PacketPage is faster, simpler and more efficient. In addition, the CS8900A has been designed for very low noise emission, thus shortening the time required for EMI testing and qualification. Complete Support The CS8900A comes with a suite of software drivers for immediate use with most industry standard network operating systems. In addition, complete evaluation kits and manufacturing packages are available, significantly reducing the cost and time required to produce new Ethernet products.

To boost performance further, the CS8900A includes several key features that increase throughput and lower CPU overhead, including: • • • • StreamTransfer cuts up to 87% of interrupts to the host CPU during large block transfers. Auto-Switch DMA allows the CS8900A to maximize throughput while minimizing missed frames. Early interrupts allow the host to preprocess incoming frames. On-chip buffering of full frames cuts the amount of host bandwidth needed to manage Ethernet traffic.
