GENERAL DESCRIPTION

The LAN83C171 EPIC/XF is a high-performance and a low CPU utilization Ethernet network controller designed to interface directly to the PCI Local Bus on one side and to the 802.3 standard Media Independent Interface (MII) on the other side. The network interface can also be configured to communicate directly with the LAN83C694 10BASE-T transceiver.
