描述 Description

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
\u0001Single-chip Ethernet controller for the Peripheral Component Interconnect (PCI) local bus
\u0001Supports ISO 8802-3 (IEEE/ANSI 802.3) and Ethernet standards
\u0001Direct interface to the PCI local bus (Revision 2.0 compliant)
\u0001High-performance 32-bit Bus Master architecture with integrated DMA buffer management unit for low CPU and bus utilization
\u0001Software-compatible with AMD PCnet family, LANCE/C-LANCE, and Am79C900 ILACC register and descriptor architecture
\u0001Compatible with PCnet family driver software
\u0001Full-duplex operation for increased network bandwidth
\u0001Big endian and little endian byte alignments supported
\u00013.3 V/5 V signaling for PCI bus interface
\u0001Low-power CMOS design with two sleep modes allows reduced power consumption for critical battery-powered applications and Green PCs
\u0001Integrated Magic Packet™support for remote wake up of Green PCs
\u0001Individual 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
