Introduction
Features
Watchdog Timer
The Watchdog Timer function allows your application to regularly “clear” the sys-
tem at the set time interval. If the system hangs or fails to function, it will reset
at the set time interval so that your system will continue to operate.
CompactFlash
The system board is equipped with the CompactFlash TM socket for inserting a
CompactFlash TM card. CompactFlash TM card is a small removable mass storage
device designed with flash technology - a non-volatile storage solution that does
not require a battery to retain data indefinitely. The CompactFlash
TM technology
is widely used in products such as portable and desktop computers, digital cam-
eras, handheld data collection scanners, PDAs, Pocket PCs, handy terminals and
personal communicators.
DDR2
DDR2 is a higher performance DDR technology whose data transfer rate delivers
bandwidth of 4.3 GB per second and beyond. That is twice the speed of the con-
ventional DDR without increasing its power consumption. DDR2 SDRAM modules
work at 1.8V supply compared to 2.6V memory voltage for DDR modules. DDR2
also incorporates new innovations such as the On-Die Termination (ODT) as well
as larger 4-bit pre-fetch against DDR which fetches 2 bits per clock cycle.
Graphics
The Intel ® 945GSE Express Chipset features an integrated 32-bit 3D graphics en-
gine based on the Intel ® Graphics Media Accelerator 950 architecture; delivering
sophisticated graphics for large display applications. Graphics interfaces such as
VGA and dual-channel LVDS support multiple graphics display options.
S/PDIF
S/PDIF is a standard audio file transfer format that transfers digital audio sig-
nals to a device without having to be converted first to an analog format. This
prevents the quality of the audio signal from degrading whenever it is converted
to analog. S/PDIF is usually found on digital audio equipment such as a DAT
machine or audio processing device. The S/PDIF connector on the system board
sends surround sound and 3D audio signal outputs to amplifiers and speakers
and to digital recording devices like CD recorders.
Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification.
With speed of up to 150MB/s, it improves hard drive performance faster than the
standard parallel ATA whose data transfer rate is 100MB/s.
