General Description
The IP100A LF is a single-chip, full duplex,
10/100Mbps Ethernet MAC + PHY incorporating a
32-bit PCI with bus master support. The IP100A
LF is designed for use in a variety of applications
including workstation NICs, PC motherboards,
and other systems utilizing a PCI bus that require
network connectivity to an Ethernet or Fast
Ethernet LAN.
The IP100A LF includes a PCI bus interface unit,
IEEE 802.3 compliant MAC, transmit and receive
FIFO buffers, IEEE 802.3 compliant 100BASE-TX,
10BASE-T, and 100BASE-FX PHY, serial
EEPROM interface and LED drivers.
The IP100A LF 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 IP100A LF. Network management statistics
are also recorded, and host access to registers of
the PHY device are facilitated through the IP100A
LF’s PCI interface.
The IP100A LF supports features for use in
“Green PCs” or systems where control over
system power consumption is desired. The
IP100A LF supports several power down states,
and the ability to issue a system “wake event” via
reception of unique, user defined Ethernet frames.
In addition, the IP100A LF can assert a wake
event in response to changes in the Ethernet link
