who are using this device to design an Ultra160 SCSI port for PCI-based

personal computers, workstations, servers or embedded applications.

Organization

This document has the following chapters and appendixes:

•Chapter 1, Introduction, describes the general information about the

LSI53C1000.

•Chapter 2, Functional Description, describes the main functional

areas of the chip in greater detail, including the interfaces to the

SCSI bus and external memory.

•Chapter 3, Signal Descriptions, contains the pin diagram and signal

descriptions.

•Chapter 4, Registers, describes each bit in the operating registers,

and is organized by register address.

•Chapter 5, SCSI SCRIPTS Instruction Set, deﬁnes all of the SCSI

SCRIPTS instructions that are supported by the LSI53C1000.

•Chapter 6, Speciﬁcations, contains the electrical characteristics and

AC timing diagrams.

•Appendix A, Register Summary, is a register summary.

iv Preface

•Appendix B, External Memory Interface Diagram Examples,

contains several example interface drawings for connecting the

LSI53C1000 to external ROMs.
