DP83820 10/100/1000 Mb/s PCI Ethernet Network Interface Controller PRELIMINARY February 2001 DP83820 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.
3V powered I/Os with 5V tolerant inputs — JTAG Boundary Scan supported General Description DP83820 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 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.
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 ...
