1.1 General Description
Chapter 1
Introduction
This chapter is divided into the following sections:
The LSI53CF92A Fast SCSI Controller (FSC) is a high performance
CMOS device designed to maximize SCSI transfer rates. This device
conforms to American National Standards Institute (ANSI) standards
X3.131-1986 (SCSI-1) and X3.131-199X (SCSI-2). The FSC includes the
basic functionality of earlier SCSI devices, plus additional features
including Fast SCSI, a 24-bit transfer counter, a part-unique ID code, and
SCSI-Configured AutoMatically (SCAM) Level 1 and 2 capability.
The LSI53CF92A is a second generation SCSI controller that reduces
protocol overhead by performing common SCSI sequences in hardware, in
response to a single command. The LSI53CF92A operates at sustained
data transfer rates up to 10 Mbytes/s in synchronous mode and 5 Mbytes/s
in asynchronous mode. The LSI53CF92A has on-chip 48 mA drivers for
Single-Ended (SE) transmission and is offered in a 64-pin Plastic Quad
Flat Pack (PQFP) or a 64-pin Thin Quad Flat Pack (TQFP) package.
The microprocessor and DMA bus widths are eight bits. The FSC
microprocessor bus can operate in either a multiplexed or nonmultiplexed
mode, depending on the state of the MODE pin. See Figures
for more details.
