ETC LSI53C1000R

LSI53C1000R
ULTRA160 SCSI CONTROLLER
BENEFITS
• Provides a low-risk upgrade
path to next level of performance
• Paves the way to Ultra320 SCSI
by being pin compatible with
the LSI53C1020 PCI-X to Single
Channel Ultra320 SCSI Controller
• Allows you to design one board
for present and future technologies
PCI-SINGLE CHANNEL ULTRA160
SCSI CONTROLLER OVERVIEW
• Preserves SCSI investment
The LSI53C1000R PCI-Single Channel Ultra160 SCSI Controller provides
a low-risk upgrade path to Ultra320 SCSI and to PCI-X. Because the
LSI53C1000R is packaged in the same BGA as the LSI53C1020 PCI-X to
Single Channel Ultra320 SCSI Controller, a motherboard can be designed
now to accept either part without the need for redesign. The LSI53C1000R
is identical in function to the proven LSI53C1000 PCI-Single Channel
Ultra160 SCSI Controller.
• Reduces time to market
• Provides complete end-to-end
protection of the SCSI I/O with
Cyclic Redundancy Check (CRC)
and Asynchronous Information

KEY APPLICATIONS
• Servers – Internet/Intranet network, video, e-mail, printing, database
management, and financial applications
• Workstations – CAD/CAM, industrial simulation, etc.

FEATURES
ULTRA160 SCSI FEATURES
• Pin compatible with LSI53C1020
Ultra320 controller
Double transition clocking enables throughput of up to 160 MBps without
increasing the interface clock rate.
• Functionally identical to
LSI53C1000 Ultra160 controller
Cyclic Redundancy Check (CRC) improves the reliability of SCSI data
transmission through enhanced detection of communication errors. CRC
provides extra data protection for marginal cable plants and external
devices. CRC is the best way to ensure data protection during hot plugging.
It uses the same proven CRC algorithm used by FDDI, Ethernet, and Fibre
Channel, and detects all single bit errors, all double bit errors, all odd number
of errors, and all burst errors up to 32 bits long. To provide complete endto-end protection of the SCSI I/O, AIP protects all non-data phases, augmenting
the CRC feature of Ultra160.
• No external memory required
• 64-bit, 33/66 MHz PCI interface
• Theoretical 528 MBps zero
wait state transfer rate
• 64-bit addressing supported
through Dual Address
Cycle (DAC)
• Compliant with PCI 2.2, PCI
Power Management 1.1
and PC99
SureLINK domain validation technology detects the configuration of the
SCSI bus and automatically tests and adjusts the SCSI transfer rate to optimize
interoperability. The LSI53C1000R exceeds Ultra160 by providing not only
Basic (Level 1) and Enhanced (Level 2) domain validation, but adds Margined
(Level 3) domain validation. This enhancement margins LVD drive strength
and clock signal timing characteristics to identify marginal Ultra160 systems.
• Supports Ultra160 SCSI
• Double transition clocking for
160 MBps throughput
• CRC
• Domain validation
• Comprehensive SureLINK
domain validation
• Basic (Level 1) with
inquiry command
• Enhanced (Level 2) with
read/write buffer
• Margined (Level 3) with

HARDWARE/SOFTWARE OVERVIEW
PCI Interface
The host PCI interface complies with PCI Local Bus Specification Revision
2.2, and implements a 64-bit/66 MHz PCI bus. It is backward compatible
with 32-bit/33 MHz buses. Additionally, support for DAC is provided.
The LSI53C1000R complies with PCI Power Management Interface
Specification Revision 1.1 and PC 99, supporting power states D0, D1, D2,
D3hot and D3cold, power management capabilities registers, and programmable values for PCI Subsystem Vendor ID and Subsystem ID. Extended
access cycles (Memory Read Line, Memory Read Multiple, and Memory Write
and Invalidate) are also supported.
SCSI Processor
The LSI53C1000R supports wide Ultra160 SCSI synchronous transfer
rates up to 160 MBps on a LVD SCSI bus. Integrated LVDlink™ transceivers
support both LVD and single-ended signals with no external transceivers
required. Fast SCSI, Ultra SCSI, Ultra2 SCSI, and Ultra160 SCSI are all
supported by the LSI53C1000R.
An on-chip SCSI clock quadrupler allows the chip to achieve Ultra160
SCSI transfer rates with an input frequency of 40 MHz. The 8 KB of internal
RAM for SCRIPTS™ instruction storage allow all accesses to remain internal,
reducing the time spent on the PCI bus. A 944-byte DMA FIFO allows the
device to efficiently burst up to 512 bytes across the PCI bus. SCSI bus
phase mismatches are handled in SCRIPTS, reducing CPU utilization.

MEMORY INTERFACES
The LSI53C1000R supports up to 1 MB of external expansion ROM
through a parallel interface, for add-in card designs. For ease of software
development and field upgrades of the ROM, the interface supports local
programming of FLASH memory. A serial 2-wire interface provides a
connection to an external serial EEPROM for storing Subsystem Vendor ID
and Subsystem ID.

SOFTWARE
The LSI53C1000R is supported with the proven SDMS software. SDMS
software enables the performance enhancements of Ultra160 data transfer
speed increases and improved PCI bus utilization capabilities included in the
LSI53C1000R. The LSI53C1000R reliability capabilities of AIP and CRC are
enabled and managed by the SDMS software. SDMS software implements
the manageability improvements of the LSI Logic SureLINK domain validation
technology. SureLINK technology extends standard domain validation with
the addition of full cable plant margining. The cable plant margining capability,
exclusive to LSI Logic’s Ultra160 solution, includes end-to-end margining from
the LSI53C1000R through LSI Logic’s LSI53C180 SCSI bus expander to the
target device. The domain validation capability of SDMS software is available
as an independent application as well as integrated in the DMI 2.0 based
system management solution for enterprise class implementations. SDMS software
includes BIOS and OSV certified drivers for all major operating systems
including DOS with ASPI support, Windows 95/98, Windows NT/2000,
UnixWare, OS/2, NetWare, Solaris, and Linux. A complete set of SCSI utilities
rounds out the software solution, which includes a DMI 2.0 based system
management software for Windows NT, NetWare, UnixWare, Solaris and
Linux, and a stand-alone or snap-in DMI browser applet and SureLINK applet.
