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

802.3compliant 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.
