EPIA EN-Series Operating Guide

VIA EPIA EN-Series Overview

The VIA EPIA EN-Series Mini-ITX Mainboard is an ultra compact native x86 platform optimized for
today's demanding embedded and productivity applications. The mainboard is based on the VIA CN700
chipset featuring an embedded hardware MPEG-2 accelerator and integrated VIA UniChrome™ Pro
2D/3D graphics for rich digital media performance. With the sizable memory bandwidth of DDR2 533MHz
SDRAM DIMM and the high data transfer speeds of ATA-133 and further enhanced by support of 8­Channel AC’97 codec for Smart 5.1 surround sound and SPDIF, the VIA EPIA EN-Series delivers the
increased performance levels required by today’s embedded digital media applications.

The latest in high-bandwidth connectivity is supported with four USB 2.0 ports, as well as a COM port and
has one 10/100/1000 Fast Ethernet port for extended broadband connectivity. The VIA EPIA EN-Series
also has one PCI slot for expandability options. The VIA EPIA EN-Series is compatible with a full range
of Mini-ITX chassis as well as FlexATX and MicroATX enclosures and power supplies.

The VIA EPIA EN-Series is fully compatible with Microsoft® and Linux operating systems and is available
in a variety of configurations, including the fanless VIA Eden™ V4 Bus NanoBGA2 processor for silent
system designs and the latest VIA C7™ V4 Bus NanoBGA2 processor for small, low power and secure
x86 processor platforms.

Power Specifications

The EPIA EN utilizes an industry standard 20-pin ATX main connector to the power supply. Due to the
EPIA EN platform’s ultra low power requirements a 90 – 120 Watt ATX power supply is ample for even
the heaviest of multimedia system applications.
