DESCRIPTION
The CS8900A is a low-cost Ethernet LAN Controller op-
timized for Industry Standard Architecture (ISA)
Personal Computers. Its highly-integrated design elimi-
nates 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.
Its
unique
automatically adapts to changing network traffic pat-
terns and available system resources. The result is
increased system efficiency.
PacketPage
architecture
The CS8900A is available in a 100-pin TQFP package-
ideally suited for small form-factor, cost-sensitive
Ethernet applications. With the CS8900A, system engi-
neers can design a complete Ethernet circuit that
occupies less than 1.5 square inches (10 sq. cm) of
board space.
