CS8900-CQ Datasheet PDF - Cirrus Logic

Description
The CS8900 is a low-cost Ethernet LAN Controller optimized for Industry Standard Architecture (ISA) Personal Computers. Its highly-integrated design eliminates the need for costly external components required by other Ethernet controllers. The CS8900 includes on-chip RAM, 10BASE-T transmit and receive filters, and a direct ISA-Bus interface with 24 mA Drivers.
