Features: SN75C091A SCSI Bus Controller
Data Manua l
The SN75C091A provides the capability to in terface a microprocessor subsystem to t he ANSI Small Computer Systems Interfac e (SCSI). This single-ended SCSI implem entation acts as one of up to eight nod es communicating over a maximum six-met er bus as detailed in the SCSI specific ation (ANSI X3.131-1986). Its microproc essor and DMA interfaces allow the SN75 C091A SCSI Bus Controller (SBC) to be u sed in a variety of host or peripheral applications.
This document is not int ended to serve as a tutorial on the Sma ll Computer Systems Interface bus; user s should refer to ANSI X3.131-1986 for detailed information regarding the SCSI bus.
