Manufacturer: National Semiconductor (now Texas Instruments)

Overview: DP83821 10/100/1000 Mb/s PCI Ethernet Network Interface Controller PRELIMINARY February 2001 DP83821 10/100/1000 Mb/s PCI Ethernet Network Interface Controller — Virtual LAN (VLAN) and long frame support. VLAN tag insertion support for transmit packets. VLAN tag 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. — Statistics gathered for support of RFC 1213 (MIB II), RFC 1398 (Ether-like MIB), IEEE 802.3 LME, reducing CPU overhead for management. — Internal 8 KB Transmit and 32 KB Receive data FIFOs — Supports Jumbo packets — Serial EEPROM port with auto-load of configuration data from EEPROM at power-on — Flash/PROM interface for remote boot support — Full Duplex support for 10/100/1000 Mb/s data rates — 208-pin PQFP package — Low power CMOS design — 3.

General Description

DP83821 is a single-chip 10/100/1000 Mb/s Ethernet Controller for the PCI bus.

It is targeted at highperformance adapter cards and mother boards.

The DP83821 fully implements the V2.2 33 MHz, 32-bit PCI bus interface for host munications with power management support.

Key Features

  • IEEE 802.3 Compliant, 33 Mhz, 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.
  • Flexible, programmable Bus master - burst sizes of up to 256 dwords (1024 bytes).
  • 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 Device Class Power Man.
