Vega86-6240 Vega86EBX CPU Module 2
1.2 Product Description
The Vega86 Single-Board-Computer series (powered by VIA Mark CoreFusion processor) offers
high performance, cost-effectiveand energy efficient processor with integrated ProSavage4 SA
graphics controller, which is the powerful embedded x86 platform for Windows XP Embedded,
WEPOS, and embedded Linux application.
The complete board consists of the Mark CoreFusion processor and the VT82C686B PCI-ISA
South Bridge, Realtek RTL8100B 10/100 Fast Ethernet Controller, etc. The processor integrates
VIA’s high-performance ProSavage4 3D / 2D graphics controller, LCD and Flat Panel display
interfaces, with further superior performance between the CPU, SDRAM and PCI bus with
pipelined, burst, and concurrent operation. The South Bridge is PC98 / PC99 compliant with
integrated UltraDMA-100/ 66 / 33 IDE, 2 (or 3) USB (1.1) ports, Super-I/O functions (floppy disk
drive interface and serial / parallel ports), and AC-97 link supporting digital audio functions.
The Vega86 SBC supports SDRAM up to 256MB. As to the DRAM controller, it meets the
standard PC133 Synchronous DRAM (SDRAM). The Synchronous DRAM interface allows zero
wait state bursting between the SDRAM and the data buffers at 133MHz.
The Vega86 SBC integrates S3 Graphics and 128-bit ProSavage4 graphics accelerators that
bring mainstream graphics performance to the Value PC with leading-edge 2D, 3D and DVD
video acceleration into a cost effective package.Vega86 SBC also combines the industry’s first
integrated AGP 4X solution with Microsoft Direct-X texture compression and massive 2Kx2K
textures to deliver unprecedented 3D performance and image quality for the Value PC mobile
market.
Vega86 SBC’s South Bridge supports four levels (doubleword) of line buffers, DMA transfers and
delay transaction to allow efficient PCI bus utilization and (PCI-2.2 compliant). The VT82C686B
also includes anintegrated Super I/O, integrated DS12885 style real time clock with extended
256 byte CMOS RAM, integrated master mode enhanced IDE controller with full scatter / gather
capability, integrated two (or three) USB (1.1) interface with root hub and two function ports with
built-in physical layer transceivers, Distributed DMA support and integrated AC-97 link for basic
audio functions.
Regarding the network architecture application, Vega86 SBC equips with the Realtek RTL8100B,
which is a highly integrated, cost-effective single-chip Fast Ethernet controller able to provide
32-bit performance, PCI bus master capability, and full compliance with IEEE 802.3u
10/100Base-T specifications and IEEE 802.3x Full Duplex Flow Control.
