SN75C091A SCSI Bus Controller
Data Manual
1 Introduction
1.1 Description
The SN75C091A provides the capability to interface a microprocessor subsystem to the ANSI Small Computer Systems Interface (SCSI). This single-ended SCSI implementation acts as one of up to eight nodes communicating over a maximum six-meter bus as detailed in the SCSI specification (ANSI X3.131-1986). Its microprocessor and DMA interfaces allow the SN75C091A SCSI Bus Controller (SBC) to be used in a variety of host or peripheral applications.
This document is not intended to serve as a tutorial on the Small Computer Systems Interface bus; users should refer to ANSI X3.131-1986 for detailed information regarding the SCSI bus.
