descriptor architecture

s Compatible with Am2100/Am1500T and Novell®

NE2100/NE1500

driver

software

s High-performance Bus Master architecture with

integrated DMA Buffer Management Unit for

low CPU and bus utilization

s Big endian byte alignment supported

s Single +5 V power supply operation

s Low-power, CMOS design with sleep modes

allows reduced power consumption for critical

battery powered applications and Green PCs

s MicrowireTM EEPROM interface supports

jumperless design

s Individual 136-byte transmit and 128-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 packet rejection

— Automatic deletion of received collision frames

s Look-Ahead Packet Processing (LAPP)

concept allows protocol analysis to begin

before end of receive frame

s Integrated Manchester Encoder/Decoder

s Provides integrated Attachment Unit Interface

(AUI) and 10BASE-T transceiver with automatic

port selection

s Automatic Twisted-Pair receive polarity detec-

tion and automatic correction of the receive

polarity

s Optional byte padding to long-word boundary

on receive

s Dynamic transmit FCS generation programma-

ble on a frame-by-frame basis

s Internal/external loopback capabilities

s Supports the following types of network

interfaces:

— AUI to external 10BASE2, 10BASE5,10BASE-T

or 10BASE-F MAU

— Internal 10BASE-T transceiver with Smart

Squelch to Twisted-Pair medium

s NAND Tree test mode for connectivity testing

on printed circuit boards

s 132-pin PQFP package

GENERAL DESCRIPTION

The PCnet-PCI single-chip 32-bit Ethernet controller is

a highly integrated Ethernet system solution designed to

address high-performance system application require-

ments. 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. The

bus-master architecture provides high data throughput

in the system and low CPU and system bus utilization.

The PCnet-PCI controller is fabricated with AMD’s ad-

vanced low-power CMOS process to provide low oper-

ating

and

standby

current

for

power

sensitive

applications.

The PCnet-PCI controller is a complete Ethernet node

integrated into a single VLSI device. It contains a bus in-

terface unit, a DMA buffer management unit, an IEEE

802.3-defined Media Access Control (MAC) function, in-

dividual 136-byte transmit and 128-byte receive FIFOs,

an IEEE 802.3-defined Attachment Unit Interface (AUI)

and Twisted-Pair Transceiver Media Attachment Unit

(10BASE-T MAU), and a Microwire EEPROM interface.

The PCnet-PCI controller is also register compatible

with the LANCE (Am7990) Ethernet controller, the

C-LANCE (Am79C90) Ethernet controller, the ILACC

(Am79C900) Ethernet controller, and all Ethernet
