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.

The

LAN83C171

implements

802.3

Media

Access Control functions.

It is capable of

running at Ethernet rates of both 100Mb/s and

10Mb/s. An MII compliant serial management

interface is provided to control external media

dependent transceivers.

The LAN83C171 is a

two channel bus master (one for transmit, one

for receive) capable of transferring data at the

maximum PCI transfer rate of 132Mbps.

The

LAN83C171 has several features designed to

minimize CPU utilization, including the optional

Receive

Lookahead

Buffering

Mode,

which

eliminates the need to re-copy the data from one

host memory location to another.
