EPIA LT-Series Operating Guide

VIA EPIA LT-Series Overview

The VIA EPIA LT-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 CX700 chipset featuring an embedded hardware MPEG-2 accelerator and
integrated VIA UniChrome™ Pro II 3D/2D graphics for rich digital media performance. With
the sizable memory bandwidth of DDR2 533MHz SDRAM DIMM and the high data transfer
speed of ATA-133 and further enhanced by support of VIA VT1708A High Definition Audio
codec, the VIA EPIA LT-Series delivers the increased performance levels required by today’s
embedded digital media applications.

The latest in high-bandwidth connectivity is supported with 4 USB 2.0 ports, as well as a
COM port and has two 10/100 Fast Ethernet ports for extended broadband connectivity.
The VIA EPIA LT-Series also has one PCI slot for expandability options. The VIA EPIA LT­Series is compatible with a full range of Mini-ITX chassis as well as FlexATX and MicroATX
enclosures and power supplies.

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

Power Specifications

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