GENERAL DESCRIPTION
The ST201 is a single-chip, full duplex, 10/
100Mbps Ethernet MAC incorporating a 32-bit PCI
including  bus master support. The ST201 is
designed for use in a variety of applications rang-
ing from workstation  NICs, networking equipment
such as switches or routers, and other systems uti-
lizing a PCI bus which require network connectivity
to an Ethernet or Fast Ethernet LAN.
The ST201 includes a PCI bus interface unit, IEEE
802.3 compliant MAC, transmit and receive  FIFO
buffers, IEEE 802.3u compliant  MII, serial Electri-
cally EEPROM interface, expansion ROM inter-
face, and LED drivers.
The ST201 implements a rich set of control and
status registers. Accessible via the PCI interface,
these registers provide a host system  visibility into
the features and operating state of the ST201. Net-
work management statistics are also recorded, and
host access to registers of the PHY device are
facilitated through the ST201’s PCI interface.
The ST201 supports several features for use in
“Green PCs” or systems where control over system
power consumption is desired. The ST201 sup-
ports several power down states, and the ability to
issue a system “wake event” via reception of
unique, user defined Ethernet frames. In addition,
the ST201 can assert a wake event in response to
changes in the Ethernet link status.
