New Features in the LSI53C896 – The LSI53C896 is functionally
similar to the LSI53C876 PCI to Dual Channel SCSI Multifunction
Controller, with added support for Ultra2 SCSI. Some software
enhancements, and the use of LVD, are needed to enable the chip to
transfer data at Ultra2 SCSI transfer rates.
•
64-bit PCI Interface.
•
Able to handle SCSI phase mismatches in SCRIPTS without
interrupting the CPU.
•
Two wide Ultra2 SCSI channels in a single package.
•
Separate 8 Kbyte internal SCRIPTS RAMs.
•
JTAG boundary scanning.
•
RAID ready alternative interrupt signaling.
•
PC99 Power Management – including automatic download of
Subsystem Vendor ID and Subsystem ID, and PCI power
management levels D0, D1, D2, and D3.
