GENERAL DESCRIPTION

The PCnet-ISA II controller, a single-chip Ethernet con-

troller, is a highly integrated system solution for the

PC-AT Industry Standard Architecture (ISA) architec-

ture. It is designed to provide flexibility and compatibil-

ity with any existing PC application. This highly

integrated VLSI device is specifically designed to re-

duce parts count and cost, and addresses applications

where higher system throughput is desired. The PC-

net-ISA II controller is fabricated with AMD’s advanced

low-power CMOS process to provide low standby cur-

rent for power sensitive applications.

The PCnet-ISA II controller can be configured into one

of three different architecture modes to suit a particular

PC application. In the Bus Master mode, all transfers

are performed using the integrated DMA controller.

This configuration enhances system performance by

allowing the PCnet-ISA II controller to bypass the plat-

form DMA controller and directly address the full 24-bit

memory space. The implementation of Bus Master

mode allows minimum parts count for the majority of

PC applications. The PCnet-ISA II can also be config-

ured as a Bus Slave with either a Shared Memory or

Programmed I/O architecture for compatibility with

low-end machines, such as PC/XTs that do not support

Bus Masters, and high-end machines that require local

packet buffering for increased system latency.

The PCnet-ISA II controller is designed to directly inter-

face with the ISA or EISA system bus. It contains an

ISA Plug and Play bus interface unit, DMA Buffer Man-

agement Unit, 802.3 Media Access Control function,

individual 136-byte transmit and 128-byte receive

FIFOs, IEEE 802.3 defined Attachment Unit Interface

(AUI), and a Twisted Pair Transceiver Media Attach-

ment Unit. Full duplex network operation can be

enabled on any of the device’s network ports. The PC-

net-ISA II controller is also register compatible with the

LANCE (Am7990) Ethernet controller and PCnet-ISA

(Am79C960). The DMA Buffer Management Unit sup-

ports the LANCE descriptor software model. External

remote boot and Ethernet physical address PROMs

and Electrically Erasable Proms are also supported.

This advanced Ethernet controller has the built-in

capability of automatically selecting either the AUI port

or the Twisted Pair transceiver. Only one interface is

active at any one time. The individual 136-byte transmit

and 128-byte receive FIFOs optimize system over-

head, providing sufficient latency during packet trans-

mission and reception, and minimizing intervention

during normal network error recovery. The integrated

Manchester encoder/decoder eliminates the need for

an external Serial Interface Adapter (SIA) in the node

system. If support for an external encoding/decoding

scheme is desired, the embedded General Purpose

Serial Interface (GPSI) allows direct access to/from the

MAC. In addition, the device provides programmable

on-chip LED drivers for transmit, receive, collision,

receive polarity, link integrity and activity, or jabber

status. The PCnet-ISA II controller also provides an

External Address Detection Interface

(EADI

) to

allow external hardware address filtering in internet-

working applications.

For power sensitive applications where low stand-by

current is desired, the device incorporates a sleep

function to reduce over-all system power consumption,

excellent for notebooks and Green PCs. In conjunction

with this low power mode, the PCnet-ISA II controller

also has integrated functions to support Magic Packet,

an inexpensive technology that allows remote wake up

of Green PCs.

With the rise of embedded networking applications

operating in harsh environments where temperatures

may exceed the normal commercial temperature (0

to +70

C) window, an industrial temperature (–40

C to

+85

C) version is available in all two packages; 132-pin

PQFP and 144-pin TQFP. The industrial temperature

version of the PCnet-ISA II Ethernet controller is

characterized across the industrial temperature range

(–40

C to +85

C) within the published power supply

specification (4.75 V to 5.25 V; i.e.,
