GENERAL DESCRIPTION

The Z5380 SCSI (Small Computer System Interface) con-

troller is designed to implement the SCSI protocol as

defined by the ANSI X3.131-1986 standard, and is fully

compatible with the industry standard 5380. It is capable

of operating both as a Target and as an Initiator. Special

high-current open-drain outputs enable the Z5380 to di-

rectly interface to, and drive, the SCSI bus. The Z5380 has

the necessary interface hook-ups which allows the system

CPU to communicate with it like any other peripheral

device. The CPU can read from, or write to, the SCSI

registers which are addressed as standard or memory-

mapped I/Os (Figure 1).

detects a bus condition that requires attention. It also

supports arbitration and reselection. The Z5380 has the

proper hand-shake signals to support normal and block

mode DMA operations with most DMA controllers avail-

able (Figure 2).

Notes:

All Signals with a preceding front slash, "/", are active Low, e.g.,

B//W (WORD is active Low); /B/W (BYTE is active Low, only).
