VIA Fire IIM VT6308P/S 1394 Host Controller
complete small package single chip PCI solution for high-speed,
low power seamless plug and play connections to the latest
IEEE 1394 enabled devices.
The IEEE 1394 high-speed serial bus (known as 'Firewire™')
is a leading PCI peer-to-peer interconnect system and
is widely acclaimed as the primary interface for digital
audio and video applications. The IEEE 1394a specification
enables hot-pluggable high volume connections to PC peripherals
such as printers and hard disk drives, multimedia appliances,
and consumer electronics devices such as game consoles
and video cameras.
The VIA Fire IIM VT6308P/S is a single-chip, low power
2-port IEEE 1394 host controller providing PC systems
with high speed, flexible connectivity to a wide range
of peripherals and consumer electronics. Supporting the
latest high speed IEEE 1394a standards, the VIA VT6308P/S
can detect connected device types and automatically configure
data speeds to 100, 200, or 400 Mbps, transmitting both
asynchronous and isochronous (real-time) data packets.
With an integrated physical and link layer, the VIA VT6308P/S
is equipped with 32-bit PCI bus interface that features
advanced power management, and cardbus support. On-board
chip logic performs bus initialization and arbitration
functions allowing for easy plug-and-play connections,
and a DMA engine supports high performance data transfer
for media disk drives.
The VIA VT6308 is compliant with the latest IEEE 1394
standards with full 1394a P2000 support, and has an OHCI
compliant programming interface with support for I2C EEPROMs
and 4-Wire Serial ROMs. The VIA VT6308P/S has VIA and OHCI software driver support built into all recent Microsoft®
Windows® operating systems.
To minimize power consumption the VIA VT6308P/S has
a programmable PCI power management mode that shuts down
power to unconnected ports, while a sleep function maximizes
the power efficiency of connected ports. The chip is manufactured
using a low power 0.20 micron process to further reduce
operating power requirements.
Combining the single chip design with a powerful feature
set, the VIA VT6308P/S is the ideal solution for OEMs
and motherboard manufacturers looking for a small package,
low power and cost effective controller solution to add
IEEE 1394 connectivity to their product line-up.
Benefits of VIA 1394
Single chip design with full 'plug and play' capabilities
for integration into PC systems and consumer electronics,
equipped with an Open HCI interface and logic to perform
bus initialization and arbitration functions.
Features 2 ports supporting transmission rates up to
400 Mbps enabling the use of multiple high bandwidth
peripherals running simultaneously.
Low power consumption is provided by an improved 0.20
micron manufacturing process, enhanced by a programmable PCI power management mode with sleep function for connected
ports and inactive port disabling.
Interoperability with IEEE 1394-1995 devices, and full
P1394a 4.0 supplement support, with VIA and OHCI driver
software support incorporated into the leading operating
Ideal for Mobile Applications
Available in a compact 14x14 LQFP small package for
