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
