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 — 3.3V powered I/Os with 5V tolerant inputs — JTAG Boundary Scan supported General Description DP83821 is a single-chip 10/100/1000 Mb/s Ethernet Controller for the PCI bus. It is targeted a...
