1.1. Key Features and Benefits
1.1.1. VIA Nano™ 1.2GHz Processor
The VIA Nano is a 64-bit superscalar x86 processor based on a 65 nanometer process technology. Packed into an ultra
compact NanoBGA2 package (measuring 21mm x 21mm), it delivers an energy-efficient yet powerful performance, with
cool and quiet operation. The VIA Nano is ideal for embedded system applications such as industrial PCs, test machines,
measuring equipment, digital signage, medical PCs, monitoring systems, gaming machines, in-vehicle entertainment, etc.
1.1.2. VIA VX900 Chipset
The VIA VX900 Unified Digital Media Chipset is designed to enable high quality digital video streaming and DVD
playback in a new generation of fanless, small form factor PCs and IA devices. The VIA VX900 features VIA C-9 HC3
with 2D/3D graphics and video acceleration, DDR3 1066/800 MHz support, motion compensation and dual display
support to ensure a rich overall entertainment experience.
1.1.3. Flexible Power Options
The VIA EPIA-M860 comes with two power input options: ATX and DC-in. The ATX version supports standard 20-pin
ATX power supply connectors. The DC-in version requires a 12V/5A max input. The AC/DC adapter can be purchased
as an option with the DC-in version. The DC-in version also has an onboard 4-pin power supply connector.
1.1.4. Modular Expansion Options
The VIA EPIA-M860 ensures long-term usability with its support for industry standard expansion options. Its support for
legacy PCI expansion cards helps to smooth and reduce the costs of transitioning to newer expansion technologies. The
VIA EPIA-M860 enables companies to slowly roll out upgrades as necessary instead of having to replace everything all
at once. This ensures that companies using the EPIA-M860 obtain the maximum benefits from its past investments in PCI
expansion cards.
The VIA EPIA-M860 also includes a 1-Lane PCI Express 2.0 expansion slot that provides protection against obsolescence.
The VIA EPIA-M860 further proves its versatility with its included Mini PCI Express slot. Companies can feel free to
design low-profile systems based on the versatile EPIA-M860.
