DESCRIPTION

The CS8900A is a low-cost Ethernet LAN Controller op-

timized for the Industry Standard Architecture (ISA) bus

and general purpose microcontroller busses. 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 ISA-Bus interface with

24 mA Drivers.

In addition to high integration, the CS8900A offers a

broad range of performance features and configuration-

options.

automatically adapts to changing network traffic pat-

terns and available system resources. The result is

increased system efficiency.

The CS8900A is available in a 100-pin LQFP package

ideally suited for small form-factor, cost-sensitive Ether-

net 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.
