GENERAL DESCRIPTION

The 32-bit PCnet-PCI II single-chip full-duplex Ethernet controller is a highly integrated Ethernet system solu

tion designed to address high-performance system application requirements. It is a flexible bus-mastering

device that can be used in any application, including network-ready PCs, printers, fax modems, and bridge/router designs.

DISTINCTIVE CHARACTERISTICS


Single-chip Ethernet controller for the Peripheral Component Interconnect (PCI) local bus


Supports ISO 8802-3 (IEEE/ANSI 802.3) and Ethernet standards


Direct interface to the PCI local bus (Revision 2.0 compliant)


High-performance 32-bit Bus Master architecture with integrated DMA buffer management unit for low CPU and bus utilization


Software-compatible with AMD PCnet family, LANCE/C-LANCE, and Am79C900 ILACC register and descriptor architecture


Compatible with PCnet family driver software


Full-duplex operation for increased network bandwidth


Big endian and little endian byte alignments supported


3.3 V/5 V signaling for PCI bus interface


Low-power CMOS design with two sleep modes allows reduced power consumption for critical battery-powered applications and Green PCs


Integrated Magic Packet™support for remote wake up of Green PCs


Individual 272-byte transmit and 256-byte receive FIFOs provide frame buffering for increased system latency and support the following features:

  — Automatic retransmission with no FIFO reload

  — Automatic receive stripping and transmit  padding (individually programmable)

  — Automatic runt frame rejection

  — Automatic selection of received collision frames
