Logic PCI to Dual Channel SCSI Host Adapter User's Guide

1-2 Using the LSIU40HVD

1.2 Features

This section provides a high level overview of the PCI Interface, the SCSI

Interface, and Board Characteristics for the LSIU40HVD.

BIOS support for this host adapter is incorporated on the board in an

8 X 64K Flash BIOS.

1.2.1 PCI Interface

The PCI interface includes these features:

• Full 32-bit DMA bus master

• Zero wait-state bus master data bursts

• Universal PCI bus voltage support

1.2.2 SCSI Interface

The SCSI interface includes these features:

• Two identical isolated SCSI channels

• 16-bit differential

• Automatically enabled active termination

• Two connectors per channel:

68-pin VHDCI external

68-pin, right-angle, high density internal with jack blocks

• Fast and Ultra SCSI data transfer capability

• SCSI termination power (TERMPWR) source with autoresetting

circuit breaker

• SCSI Conﬁgured AutoMatically (SCAM)

• Flash Electronically Erasable Programmable Read Only Memory

(EEPROM) for BIOS storage

• Serial NonVolatile Random Access Memory (NVRAM) on each

channel for user conﬁguration utility and SCAM information storage

• SCSI activity LED connector for each channel
