Brief Description
The LSI FW643E is a second-
generation 1394b Open Host
Controller Interface (OHCI) designed
specically for high-performance,
PCI Express applications. Based on
LSI’s proven TrueFire® technology,
the FW643E has enhanced perfor-
mance and power management
features to deliver improved data
transfer rates with lower power
consumption.
The FW643E is the fastest 1394b
device and the only single-chip PCI
Express 1394b device available on
the market today.
The FW643E is ideally suited
for high-end PC desktops and
notebooks, adapter cards, PC
gaming systems, external disk drive
backups, industrial vision systems,
and other applications where
reliable, high-performance, data
transfer is required.
LSI provides support for the FW643
with:
n Evaluation adapter board
n Ready-to-manufacture adapter
card reference design
n Manufacturing test utilities
n Conguration EEPROM image
