SCSI FEATURES
(Continued)
–
Channel B - high performance
16-bit bus
Low Voltage Differential mode:
Uses LVDlink technology which
supports Ultra/Ultra2 bus
speeds of up to 40 or 80 MBps
Supports up to 15 Ultra and
Ultra2 LVD devices (within the
SCSI cable limits)
Single-ended mode
Supports Fast/Ultra SCSI bus
speeds up to 20 or 40 MBps
with mixed Fast/Ultra SCSI
peripherals on the bus
Supports up to 15 Fast or
Ultra devices (within the SCSI
cable limits)
Connectors
Internal - 68-pin high-density
64K byte BIOS ROM standard
Optional 256K byte ROM for
custom BIOS applications
Uses LSI Logic
’
s SCSI TolerANT
active negation SCSI driver and
receiver technology to provide
highest signal integrity in noisy
cabling environments
Available SCAM (SCSI
Configured AutoMatically)
Level 1 functionality for SCSI
plug-and-play support

The LSI21002 PCI-to-Ultra2 SCSI host adapter automatically determines if
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.
P C I F E AT U R E S
Direct (bus master) memory access for low overhead with 32-bit burst data
transfers at 133 MBps for 32-bit PCI data transfer rates
33 MHz bus master with zero wait-state PCI transfers
Up to 128 dword PCI burst rate to maximize the PCI data transfer rate
Functions as one, 32-bit PCI DMA bus master
Two independent DMA channels with internal arbitration
Supports PCI write and invalidate, read Line, and read multiple commands
Supports Dual Address Cycles (DAC) for system memory addressability > 4GB
Complies with PCI bus power management specification, version 1.1
I N T E R R U P T S
The host adapter provides separate interrupts for each channel (channel
A routed to INTA# pin and channel B routed to INTB# pin).
S U B S Y S T E M I D
The on-board LSI53C896 controller provides PCI configuration registers
for Subsystem ID and Subsystem Vendor ID. However, it is possible for OEMs
to develop custom software and store different numbers in the on-board serial
EEPROM while maintaining a standard board configuration.

LSI Logic is a key developer and contributor to the original committees
that defined today
’
s SCSI and PCI standards. Our continuing work with other
industry leaders of core chip sets, processors, system providers, SCSI device
peripherals, BIOS, and operating systems enables us to provide users with
the utmost compatibility and interoperability. Product compatibility and inter-
operability are rigorously tested and our ISO-9001 certified fabrication facilities
assures users of the highest levels of product quality and reliability.
