Product Features
■ PCI Bus
— PCI Revision 2.3 support for 32-bit wide
interface at 33 MHz and 66 MHz
— Algorithms that optimally use advanced PCI,
MWI, MRM, and MRL commands
— CardBus Information Services (CIS) Pointer
— CLK_RUN# Signal
■ 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 operation
— IEEE 802.3ab Auto-Negotiation support
— IEEE 802.3ab PHY compliance and
compatibility. State-of-the-art DSP
architecture implements digital adaptive
equalization, echo cancellation, and cross-
talk cancellation
— 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
— Advanced packed filtering
— Jumbo frame support up to 16 KB
— IEEE 802.1q VLAN support with VLAN tag
insertion, stripping and packet filtering for
up to 4096 VLAN tags
— Descriptor ring management hardware for
transmit and receive
— Interrupt coalescing (multiple packets per
interrupt)
■ Manageability
— Manageability features: Onboard SMB port,
ASF 1.0, ACPI, Wake on LAN, and PXE
— Compliance with PCI Power Management
1.1 and ACPI 2.0 register set compliant
— SNMP and RMON statistic counters
— SDG 3.0, WfM 2.0, and PC2001 compliance
■ Additional Device
— Four activity and link indication outputs that
directly drive LEDs
— JTAG (IEEE 1149.1) Test Access Port built
in silicon
— Internal PLL for clock generation can use a
25 MHz crystal
— Programmable LED functionality
— Industrial temperature support (-40 to
+85 °C)
