LSI21002

SCSI Host Adapter

K E Y A P P L I C A T I O N S

• Workstations, high-end desktops

and servers that require high

I/O performance and legacy

peripheral support

The LSI21002 PCI-to-Ultra2 SCSI

dual channel host adapter supports a

wide variety of Fast and Ultra SCSI devices.

• Ideal for desktop configurations

that require high performance

data I/O while simultaneously

supporting existing peripherals

(CDs, scanners)

O V E R V I E W

The LSI21002 dual channel PCI-to-Ultra2 SCSI host adapter board by

LSI Logic is designed for systems using high performance disks as well as

supporting a wide variety of Fast and Ultra SCSI devices. By using the

LSI53C896 dual channel PCI-to-Ultra2 SCSI controller chip to directly interface

to the PCI and SCSI buses, the LSI21002 is able to provide the high reliability

and cost effectiveness of a single-chip design. By having two complete and

separate SCSI channels, the LSI21002 can dedicate one channel, with full

connectivity, to high performance devices and the other channel, also with

full connectivity, to legacy SCSI devices.

• Supporting mixed single-ended

and LVD SCSI devices system

applications

B E N E F I T S

• Increased performance with

support of existing systems

Matching the performance of the 32-bit PCI bus to two independent SCSI

channels, the LSI21002 host adapter provides up to 120 MBps aggregate

SCSI throughput. With LSI Logic’s LVDlink^™(Low Voltage Differential) and

TolerANT^™technology, the LSI21002 provides unmatched performance,

device connectivity and signal reliability. LVDlink is LSI Logic’s implementa-

tion of the Universal

• Complete host adapter solution

for quicker OEM time-to-market

• True multi-function, single-

chip device provides better

performance than discrete PCI-

to-PCI bridge solutions or single-

channel devices supporting dual

SCSI interfaces

Low Voltage Differential standard. At last, one board provides a powerful

dual channel, scalable, multi-tasking interface for high performance SCSI

disk drives, CD-Rs, CD-RWs, scanners, interconnect, and other single-ended

or LVD SCSI devices. The dual channels increase to connectivity to up to 30

devices without utilizing an additional PCI slot or PCI load.

• Improved reliability with single-

chip solution

• Complete software support with

BIOS and drivers for all major

operating systems

Designing systems with the LSI21002 is easy with one channel dedicated

to high performance LVD devices and the second dedicated to supporting

single-ended legacy devices. Or both channels can be used to support single-

ended devices.

• Features LSI Logic’s LVDlink

universal LVD technology

LSI21002 SCSI Host Adapter

The LSI21002 is a zero wait-state DMA bus master in 32-bit PCI bus

systems and supports PCI 64-bit Dual Address Cycles for greater system

memory addressability. Built to the PCI Universal board standards, the

LSI21002 works in 3.3 or 5 V PCI bus systems. The LSI21002 includes an

on-board configuration utility, allowing the viewing and changing of default

configuration settings for the host adapter and attached SCSI devices. It also

provides advanced ease-of-use features such as automatic termination

(depending on cable configuration) on the single-ended channel.

B E N E F I T S ( C o n t i n u e d )

• Ultra2 SCSI provides increased

connectivity (cable length and

number of SCSI devices

supported) over Ultra SCSI

• Automatic termination determined

by cabling environment provides

improved ease-of-use for the

OEM and the end user

The advanced features of the LSI21002 32-bit host adapter make it the

right choice for high-performance desktops, workstations and servers.

• Termination power supplied

through self-resetting current

limiting device

cables are attached to Channel A’s (single-ended only) SCSI connectors and

then properly enables/disables that channel’s SCSI terminators. Channel B

(LVD/SE channel) is always terminated.
