The CS8900A-IQZR is a low-cost Ethernet LAN® controller for embedded applications. Its highly integrated design eliminates the need for costly external components required by other Ethernet controllers. The CS8900A-IQZR includes on-chip RAM, 10Base-T transmit-and-receive filters and a direct ISA-Bus interface with 24 mA drivers. In addition to high integration, the CS8900A-IQZR offers a broad range of performance features and configuration options. Its unique PacketPage architecture automatically adapts to changing network traffic patterns and available system resources. The result is increased system efficiency. The CS8900A-IQZR 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.
