Product Features
■ PCI Bus
■ Host Off-Loading
— PCI revision 2.3, 32-bit, 33/66 MHz
— Algorithms that optimally use advanced PCI,
MWI, MRM, and MRL commands
— CLK_RUN# signal
— 3.3 V (5 V tolerant PCI signaling)
■ MAC Specific
— Low-latency transmit and receive queues
— IEEE 802.3x-compliant flow-control support
with software-controllable thresholds
— Caches up to 64 packet descriptors in a single
burst
— Programmable host memory receive buffers
(256 B to 16 KB) and cache line size (16 B to
256 B)
— Wide, optimized internal data path
architecture
— Transmit and receive IP, TCP, and UDP
checksum off-loading capabilities
— Transmit TCP segmentation and advanced
packed filtering
— IEEE 802.1Q VLAN tag insertion and
stripping and packet filtering for up to 4096
VLAN tags
— Jumbo frame support up to 16 KB
— Intelligent Interrupt generation (multiple
packets per interrupt)
■ Manageability
— On-chip SMBus 2.0 port
— ASF 1.0 and 2.0
— Compliance with PCI Power Management
v1.1/ACPI v2.0
— Wake on LAN* (WoL) support
— 64 KB configurable Transmit and Receive
FIFO buffers
— Smart Power Down mode when no signal is
detected on the wire
■ PHY Specific
— Integrated for 10/100/1000 Mb/s full- and
half-duplex operation
— IEEE 802.3ab Auto-Negotiation and PHY
compliance and compatibility
— Power Save mode switches link speed from
1000 Mb/s down to 10 or 100 Mb/s when on
battery power
■ Additional Device
— Four programmable LED outputs
— State-of-the-art DSP architecture implements
— On-chip power regulator control circuitry
digital adaptive equalization, echo and cross-
talk cancellation
— Automatic polarity detection
— BIOS LAN Disable pin
— JTAG (IEEE 1149.1) Test Access Port built
in silicon (3.3 V, 5 V tolerant PCI signaling)
— Automatic detection of cable lengths and
MDI vs. MDI-X cable at all speeds
■ Lead-free^a 196-pin Ball Grid Array (BGA).
Devices that are lead-free are marked with a
circled “e1” and have the product code:
LUxxxxxx.
a. This device is lead-free. That is, lead has not been intentionally added, but lead may still exist as an impurity at
<1000 ppm. The Material Declaration Data Sheet, which includes lead impurity levels and the concentration of other
Restriction on Hazardous Substances (RoHS)-banned materials, is available at:

In addition, this device has been tested and conforms to the same parametric specifications as previous versions of
the device.
