CS8920A

Advanced Product Databook

FEATURES

■ Single-Chip IEEE 802.3 Ethernet Controller with

&U\VWDOꢀ/$1 ISA

Plug-and-Play Ethernet

Controller

Direct ISA-Bus Interface

■ Implements Industry-Standard Plug and Play

■ Full Duplex Operation

DESCRIPTION

■ Auto-Negotiation of Full and Half duplex Modes

The CS8920A is a low-cost Ethernet LAN Control-

ler optimized for Industry Standard Architecture

(ISA) Personal Computers. Its highly-integrated

design eliminates the need for costly external com-

ponents required by other Ethernet controllers.

■ Recognizes Received Magic Packet™ Framesand

Requests the Processor to Power Up

■ Supported by Complete Family of Device Drivers

■ Efficient PacketPage™ Architecture Operates in

I/O and Memory Space, and as DMA Slave

In addition to high integration, the CS8920A offers

a broad range of performance features and config-

■ On-Chip RAM Buffers Transmit & Receive Frames

■ 10BASE-T Port with Internal Analog Filters

■ AUI Port for 10BASE2, 10BASE5 and 10BASE-F

■ Programmable Receive Features:

uration

options.

Its

unique

PacketPage

architecture automatically adapts to changing net-

work traffic patterns and available system

resources. The result is increased system efficien-

cy and minimized CPU overhead.

— StreamTransfer™ for Reduced CPU Overhead

— Auto-Switch Between DMA and On-Chip Memory

— Early Interrupts for Frame Pre-Processing

■ Four LED Drivers for Link Status, Full Duplex, and

The CS8920A is available in a thin 144-pin TQFP

package ideally suited for small form-factor, cost-

sensitive Ethernet applications, such as desktop

and portable motherboards. With the CS8920A,

system engineers can design a complete Plug-

and-Play Ethernet circuit that occupies less than

2.0 square inches (14 sq. cm) of board space.

LAN Activity

■ Small 144-pin TQFP package, and minimal exter-

nal components (transformer, crystal and

optional EEPROM)
