DESCRIPTION
Supply
)
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.

AUI Port for 10BASE2, 10BASE5 and 10BASE-F
Programmable Transmit Features:
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.
