Product Features

■

PCI Bus

— 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

— 64 KB configurable Transmit and Receive

FIFO buffers

PHY Specific

— Integrated for 10/100/1000 Mb/s full- and

half-duplex operation

— IEEE 802.3ab Auto-Negotiation and PHY

compliance and compatibility

— State-of-the-art DSP architecture implements

digital adaptive equalization, echo and cross-

talk cancellation

— Automatic polarity detection

— Automatic detection of cable lengths and

MDI vs. MDI-X cable at all speeds

■

Host Off-Loading

— 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

— Smart Power Down mode when no signal is

detected on the wire

— 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

— On-chip power regulator control circuitry

— BIOS LAN Disable pin

— JTAG (IEEE 1149.1) Test Access Port built

in silicon (3.3 V, 5 V tolerant PCI signaling)

Lead-free

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:

ftp://download.intel.com/design/packtech/material_content_IC_Package.pdf#pagemode=bookmarks

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

the device.
