Product Overview
The EPIA-E900 is a highly integrated Pico-ITXe board powered by a 1.2GHz VIA Eden
®
X4 processor and
VIA VX11H MSP chipset that delivers a high performance and rich multimedia features in an ultra-compact
package for a wide range of embedded system applications such as industrial automation, transportation,
medical, and infotainment.
The EPIA-E900 board is fully compatible with Microsoft
®
and Linux operating systems, and provides an
impressive I/O such as COM ports, mini HDMI
®
port, Gigabit Ethernet ports, USB 2.0 ports, USB 3.0 ports,
SATA connector for storage devices, and onboard MXM connector for an optional E900-A expansion card.
In addition, EPIA-E900 also includes one DDR3 1333 SODIMM slot that support up to 8GB memory size.
1.1. Key Features and Benefits
1.1.1. VIA Eden
®
X4 Processor
The VIA Eden
®
X4 is a 64-bit superscalar x86 multi-core processor combine on two dies. It is based on
advanced 28 nanometer process technology packed into an ultra compact NanoBGA2 package measuring
21mm x 21mm. The VIA Eden
®
X4 processor delivers a superb performance on multi-tasking, multimedia
playback, productivity and internet browsing in a low power budget. In addition, it is ideal for most of
multi-display environment, and embedded system applications.
Note:
For Windows 7 and Windows Server 2008 R2 users only:
If the user encounters the issue such as the operating system recognizing the VIA Dual-Core CPU as two
processors instead of one processor with two cores, Please download and install the hotfix released by
Microsoft to address this issue.
The downloadable hotfix is available at http://support.microsoft.com/kb/2502664
1.1.2. VIA VX11H MSP Chipset
The VIA VX11H is the fourth generation, highly integrated Media System Processor which provides high
quality digital video streaming and high definition video playback. It features the VIA C-640 DX11 3D/2D
graphics and video processor, High Definition video decoder supports DDR3 1333 controller and USB 3.0
interface.
The VIA VX11H offers superb-graphics performance, immersive visual experience, and supports DirectX
11.0 that allows realistic 3D rendering and increased visual acuity. The VIA VX11H is based on a highly
sophisticated power efficient architecture that enables such rich integration into a compact package.
1.1.3. Expansion Option
The EPIA-E900 further proves its versatility by providing an expansion MXM connector for optional
E900-A expansion card. The E900-A expansion card is carrying multiple expansion I/O such as audio jack,
USB 2.0 ports, SATA connector, PCIe slot, LVDS panel connector, DisplayPort/HDMI port, DVP port and
etc.
The companies using the EPIA-E900 with E900-A expansion card obtain the maximum benefits and enable
to slowly roll out upgrades as necessary instead of having to replace everything all at once.
