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 LAN83C175 has several features designed
to maximize throughput and minimize CPU
utilization,
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
