BENEFITS

• Pin-for-pin replacement for

LSI53C825 and LSI53C825AE

devices

• Minimal software and hardware

modifications required for Ultra

SCSI support

• Compact 160-pin PQFP reduces

board space requirements

(LSI53C875E, LSI53C875JE)

OVERVIEW

The LSI53C875E controller supports Ultra SCSI transfers, enabling the

chip to transfer SCSI data at up to 40 MBps across a 16-bit bus. Ultra SCSI

is an extension of the SCSI-3 standard that expands the bandwidth of the

SCSI bus and allows faster synchronous SCSI transfer rates-approximately

double the synchronous transfer rates of fast SCSI-2. The LSI53C875E provides

full SCSI-2 capabilities and reduces the requirements for system BIOS support

with a local memory interface. It also features LSI Logic TolerANT SCSI driver

and receiver technology, for reliable operation in all cabling environments. It

is designed to connect gluelessly to the Peripheral Component Interconnect

(PCI) bus, and supports PCI extended access cycles, enabling the system

architect to take advantage of PCI’s performance potential.

• Alternative 169 BGA package

(LSI53C875JBE)

• Direct PCI to SCSI connection

• Fully supported by SDMS

software for complete PC-based

operating system support

FEATURES

• Performs wide high-speed SCSI

bus transfers in single-ended

and differential mode up to:

• 40 MBps synchronous (Ultra)

• 14 MBps asynchronous

• SCRIPTS

™

Instruction Prefetch

• 536-byte buffer allows burst

length of up to 128 transfers

• Load and store instruction

• 4 KB static RAM for SCRIPTS

instruction storage

• 32 additional scratchpad

registers for user-defined functions

The LSI53C875E and SDMS

™

software provide a total Ultra SCSI solution

in PC and workstation environments. LSI Logic’s SDMS software package

supports the entire LSI53C8XX family of PCI-to-SCSI controllers plus a wide

range of SCSI peripheral devices.

Included in the performance-enhancing features on the LSI53C875E is

a 4 KB static RAM for SCRIPTS (the LSI Logic developed SCSI programming

language) instruction storage, which allows tailored SCSI sequences to be

executed locally. A 536-byte DMA FIFO increases system performance by

allowing burst lengths of up to 128 transfers. Other features include:

• SCRIPTS instruction prefetch which permits fetching four or eight double

words of instructions or instruction operands.

• Support for PCI extended access cycles: Memory Read Multiple, Memory

Read Line, and Memory Write and Invalidate.

LSI53C875E SCSI Controller

• Selectable IRQ disable, allowing system designers to customize their

system interface.

• SCSI Selected as ID register, improving SCRIPTS coding and system tracking.

• Load and Store instruction allows the programmer an efficient instruction

option to load data directly to/from memory and from/to an internal register,

reducing the number of l/O instructions to implement a SCRIPTS task.

FLEXIBILITY FEATURES

• Supports single-ended and differential modes

• Selectable IRQ disable

• SCSI Selected as ID register

• Support for both 3.3 volt and 5 volt PCI interfaces

• High-level programming interface (SCSI SCRIPTS)

• Allows tailored SCSI sequences to be executed from main memory

• Accommodates changes in the logical I/O interface definition

• Low-level access to all registers and all SCSI bus signals

COMPATIBILITY FEATURES

• Compiler-compatible with existing LSI53C7XX and LSI53C8XX SCRIPTS

• Full complement of LSI Logic SCSI SCRIPTS development tools available

• BIOS and driver support for hard disk, tape, CD-ROM, and removable

media peripherals for all of the major operating systems, including:

• Windows NT 4.0

• Windows 95/98

• DOS

• Linux

• NetWare

• SCO UnixWare

™

• OS/2 Warp

• Solaris
