4.8 ASC3050 Ultra SCSI
The ASC3050 is a single-side, highly integrated Ultra SCSI controller. It is specifically designed
for interfacing the PCI bus to the SCSI bus. It supports EEPROM, and information is stored in
the EEPROM telling the chip configuration and operation modes.
ASC3050 supports both synchronous and asynchronous data transfers and has a 15-byte FIFO
for synchronous offset transfer. The data transfer rate of the PCI local bus can go up to 133
MB/sec, when using a 33MHz clock. The data transfer rate of the Ultra SCSI bus can be up to 20
MB/sec, when using synchronous.
The device driver is a software program that controls a specific I/O device. The device drivers
controls the ASC3050, whcih is an I/O device for managing SCSI peripherals. The ASC3050
device drivers support a range of operating system, such as DOS, Windows, Windows 95,
Windows 98, Windows NT, Novell Netware, OS/2 Warp, and SCO UNIX, Interactive UNIX,
Linux, Unixware and Solaris.
Ultra SCSI connector supports an 8-bit, single-ended, and provides a 50-pin connector. The
connector also supports the complete range of SCSI devices, including hard disk drives, CD-
ROM drives, tape backup units, MOs, CD-ROMs, printers, and scanners.
