LSI22801

SCSI Host Adapter

B E N E F I T S

• Increased peripheral

connectivity - up to 30 devices

• Complete host adapter solution

for quick time-to-market

The LSI22801 is a PCI-dual channel

multi-function, single-ended Ultra

SCSI solution.

• True multi-function device

provides better performance

than PCI-to-PCI bridge solutions

O V E R V I E W

• Up to 80 MBps combined

synchronous transfer rate for

two 16-bit Ultra SCSI channels

The LSI22801 host adapter is a multi-function board providing two

independent single-ended Ultra SCSI channels. Both SCSI channels are

identical, offering increased connectivity without utilizing additional PCI

slots. A single board provides a powerful dual channel, multitasking interface

for Ultra SCSI peripherals such as disk, tape, CD-ROM, and other SCSI devices.

• Improved reliability with a

single chip solution

• Automatic termination determined

by cabling environment (ease of

use for OEMs and end users)

The LSI22801 leverages the LSI53C876 PCI dual channel SCSI multi-

function controller capable of connecting directly to the PCI bus, presenting

one electrical load, while functioning as a single 32-bit PCI DMA bus master.

• Complete software support

with BIOS and drivers

The LSI22801 includes an on-board configuration utility allowing

viewing and changing of default configuration settings for the host adapter

and connected SCSI peripherals.

• Termination power supplied

through self-resetting current

limiting device

The device also provides advanced features for ease of use by modifying

the on-board terminators depending on cable configuration and LEDs to

help with termination power (TERMPWR) monitoring.

• Allows custom driver development

with SCSI SCRIPTS^™

The LSI22801 has advanced features which makes it the right choice for

applications requiring up to 30 connected peripherals, or for isolating

peripheral classes (e.g. CD-ROMs and tape drives on one channel and high

performance disk drives on the other).

• Connectors for off-board SCSI

active LEDs

• Any drive in a disk array can

be used as the boot device

• On-board BIOS supports

disk drives with greater than

8-Gbyte capacity

• True multi-function device

(per PCI 2.1 Specification)

– uses only one PCI slot

The LSI22801 uses the LSI53C876 PCI dual channel SCSI multi-function

controller. This single-chip multi-function device connects directly to the PCI bus.

• Functions as one 32-bit PCI

DMA bus master

For each channel the adapter will automatically determine when cables

are attached to which connector and properly enable or disable the SCSI

terminators. The Table 1 below shows which cable combinations are allowed.

• Two independent DMA channels

with internal programmable

arbitration

One LED per channel is included to indicate the status of termination power

(TERMPWR).

• Local memory bus for FLASH

The resident menu-driven BIOS configuration utility allows the viewing and

changing of the default settings for the host adapter and SCSI devices. The

following table lists the configuration settings which can be changed. The

global settings affect the host adapter and all SCSI devices connected to it.

The host adapter boot order can be changed if more than one SCSI host

adapter solution is implemented, see Table 2.

The host adapter includes a jumper to select separate interrupts (channel A

routed to INTA# pin and channel B routed to INTB# pin) or shared interrupts

(channel A and channel B routed to INTA#/ pin).
