Section 1.5, “LSI53C896 Benefits Summary”
1.1 General Description
The LSI53C896 brings Ultra2 SCSI performance to host adapter,
workstation, and general computer designs, making it easy to add a
high-performance SCSI bus to any PCI system. It supports Ultra2 SCSI
transfer rates and allows increased SCSI connectivity and cable length
with Low Voltage Differential (LVD) signaling for SCSI devices.
The LSI53C896 has a local memory bus for local storage of the device’s
BIOS ROM in flash memory or standard EPROMs. The LSI53C896
supports programming of local flash memory for updates to BIOS. The
chip is packaged in a 329 Ball Grid Array (BGA) package. System
diagrams showing the connections of the LSI53C896 with an external
ROM or flash memory are shown in
Appendix B, “External Memory Interface Diagram Examples.”
LVDlink™ technology is the LSI Logic implementation of LVD. LVDlink
transceivers allow the LSI53C896 to perform either Single-Ended (SE) or
LVD transfers, and support external High Voltage Differential (HVD)
transceivers. The LSI53C896 integrates a high-performance SCSI core,
a 64-bit PCI bus master DMA core, and the SCSI SCRIPTS processor
