DP83820 10/100/1000 Mb/s PCI Ethernet Network Interface

Controller

— Virtual LAN (VLAN) and long frame support. VLAN tag

General Description

insertion support for transmit packets. VLAN tag

DP83820 is a single-chip 10/100/1000 Mb/s Ethernet

Controller for the PCI bus. It is targeted at high-

performance adapter cards and mother boards. The

DP83820 fully implements the V2.2 66 MHz, 64-bit PCI bus

interface for host communications with power management

support. Packet descriptors and data are transferred via

bus-mastering, reducing the burden on the host CPU. The

DP83820 can support full duplex 10/100/1000 Mb/s

transmission and reception.

detection and removal for receive packets

— 802.3x Full duplex flow control, including automatic

transmission of Pause frames based on Rx FIFO

thresholds

— IPv.4 checksum task off-loading. Supports checksum

generation and verification of IP, TCP, and UDP headers

— 802.1D and 802.1Q priority queueing support. Supports

multiple priority queues in both transmit and receive

directions.

— Extremely flexible Rx packet filtration including: single

address perfect filter with MSb masking, broadcast,

2,048 entry multicast/unicast hash table, deep packet

pattern matching for up to 4 unique patterns.

Features

— IEEE 802.3 Compliant, 66/33 Mhz, 64/32-bit PCI V2.2

MAC/BIU supports data rates from 1 Mb/s to 1000 Mb/s.

This allows support for traditional 10 Mb/s Ethernet, 100

Mb/s Fast Ethernet, as well as 1000 Mb/s Gigabit

Ethernet.

— Statistics gathered for support of RFC 1213 (MIB II),

RFC 1398 (Ether-like MIB), IEEE 802.3 LME, reducing

CPU overhead for management.

— Flexible, programmable Bus master - burst sizes of up to

256 dwords (1024 bytes)

— Internal 8 KB Transmit and 32 KB Receive data FIFOs

— Supports Jumbo packets

— BIU compliant with PC 97 and PC 98 Hardware Design

Guides, PC 99 Hardware Design Guide draft, ACPI v1.0,

PCI Power Management Specification v1, OnNow

— Serial EEPROM port with auto-load of configuration data

from EEPROM at power-on

— Flash/PROM interface for remote boot support

Device Class Power

Management Reference

Specification - Network Device Class v1.0a

— Full Duplex support for 10/100/1000 Mb/s data rates

— Wake on LAN (WOL) support compliant with PC98, — 208-pin PQFP package

PC99, and OnNow, including directed packets, Magic

Packet with SecureOn, ARP packets, pattern match

packets, and Phy status change

— Low power CMOS design

— 3.3V powered I/Os with 5V tolerant inputs

— JTAG Boundary Scan supported

— GMII/MII provides IEEE 802.3 standard interface to

support 10/100/1000 Mb/s physical layer devices

— Ten-Bit Interface (TBI) for support of 1000BASE-X
