GENERAL DESCRIPTION
The LAN83C175 EPIC/C is a high-performance
Low CPU Utilization Ethernet network controller
designed to interface directly to the CardBus
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 LAN83C175 implements 802.3 Media
Access Control functions. It is capable of
running at Ethernet rates of both 100Mbps and
10Mbps. An MII compliant serial management
interface is provided to control external media
dependent transceivers. The LAN83C175 is a
two channel bus master (one for transmit, one
for receive) capable of transferring data at the
maximum CardBus transfer rate of 132Mbps.
The LAN83C175 has several features designed
to maximize throughput and 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.
The LAN83C175 also includes a secondary
general purpose 8-bit interface with appropriate
registers, address lines and control lines. This
secondary interface provides all of the signals
required to implement a secondary function on
a CardBus adpater. An example of such a
secondary function is a 33.6Kbps or higher
speed modem design based on a Rockewell or
Lucent modem chip set.
