Product Summary

The CS8900A-CQ3 is a low-cost Ethernet LAN Controller optimized for the Industry Standard Architecture (ISA) bus and general purpose microcontroller busses. The CS8900A-CQ3’s highly integrated design eliminates the need for costly external components required by other Ethernet controllers. The CS8900A-CQ3 includes on-chip RAM, 10BASE-T transmit and receive filters, and a direct ISA-Bus interface with 24 mA Drivers.
