The ultra-compact and highly integrated VIA VB8003 uses the
Mini-ITX mainboard form-factor developed by VIA Technologies,
Inc. The mainboard enables the creation of an exciting new
generation of small, ergonomic, innovative and affordable
embedded systems. Through a high level of integration, the Mini-
ITX mainboard is only 66% of the size of FlexATX mainboard form
factor. The mainboard comes with a VIA Nano 1.6 G z
NanoBGA2 processor.
KEY COMPONENTS
VIA Nano 1.6 GHz NanoBGA2 Processor
The VIA Nano is a 64-bit superscalar processor in x86 platform
using a 65 nanometer process technology. It delivers an energy-
efficient, powerful performance, with cool and quiet operation all
within an ultra compact NanoBGA2 package measuring 21mm x
21mm. Perfectly fit for embedded system applications such as
industrial PCs, test machines, measuring equipment, digital
signage, medical PCs, monitoring systems, gaming machines, in-
vehicle entertainment, and etc. The VIA Nano also boasts of
immersive multimedia performance, connectivity and computing
applications. When combined with the all-in-one highly integrated
digital media VX800 IGP chipset, system developers can utilize an
impressive range of features for a wide range of notebook and
desktop applications.
VIA VX800 Media System Processor
The VIA VX800 all-in-one digital media IGP chipset integrates a
premium graphics engine, D audio controller, DDR2 memory
controller, 800M z FSB processor interface, and extensive I/O
capabilities in a single chip design. The VIA VX800 is based on a
highly sophisticated power efficient architecture that enables such
rich integration into a compact package with a maximum power
envelope of just 5 W.

S3 Graphics Chrome 435 ULP
The S3 Graphics Chrome 435 ULP (Ultra Low Power) graphics
processor offers superb performance-per-watt metrics, boasting
incredibly low power draw. The S3 Graphics Chrome 435 ULP
offers users an immersive visual experience without sacrificing
battery life and its support for DirectX 10.1 allows realistic 3D
rendering and increased visual acuity through improved Anti-
aliasing (AA) and Image/ Texture, higher precision formats, and
programmable lightning effects.
The S3 435 ULP also has the latest Chromotion D Video Engine
that enables acceleration for all leading video standards. It also has
the sophisticated S3 Graphics PowerWise Technology algorithms
that manage the power usage of the GPU — delivering optimal
balance between performance and power on-the-fly. The S3
Graphics PowerWise Technology brings together graphics
performance and power efficiency for embedded systems.
VIA VT1708 High Definition Audio Codec
The VIA VT1708 delivers top quality audio performance —
supporting the latest 8-channel, 24-bit, 192 k z audio content for
an all-round high-fidelity experience. Integrating stereo DACs with
a 100 dB signal-to-noise ratio, the VIA VT1708 includes features
such as a high quality headphone amplifier, enhanced recording
support, and advanced power management.
VIA VT1211 Super I/O
The VIA VT1211 is a full function Super I/O chip with a floppy disk
controller, an IEEE-1284 parallel port interface, two 16C550-UART-
based serial port interfaces, a VFIR (Very Fast IR) controller, a game
port that supports two joysticks, a MIDI interface, and a 4 MB
Flash-ROM interface.
Its integrated hardware monitor controller controls the speed of
up to two fans, monitors two fan tachometers, and five universal
analog inputs for measuring voltage or temperature. The VT1211
is ACPI ready with a hardware monitor engine built-in to monitor
system health.

Note:
System resources (such as BIOS PCI etc.) require physical
memory address locations that reduce available memory
addresses above 3 GB. This may result in less than 4 GB of
memory being available to the operating system and
applications.
With certain limitations, DVI-I (default display) can support DVI-D + CRT using a Y-cable
1. CRT will always show the same content with the primary display device from the S3G 435ULP.
2. CRT may not display correctly due to the timing limitation. Users may need to choose a specific CRT panel if
this function is desired.
