Making Your World Portable
Introduction
UMPCs (Ultra Mobile PCs) is an exciting new category of devices that can fit
comfortably into a pocket or handbag, enabling users to access and interact with their
entire digital world wherever they go. Continuing VIA’s philosophy of “Small is
Beautiful”, the VIA VX700 chipset is a crucial building block in the VIA Ultra Mobile
platform ideally complementing the VIA C7?-M processor to inspire an exciting new
category of UMPC (Ultra Mobile PC)
devices.
Creating exciting opportunities for
entertainment, productivity, and
communication focused products the VIA
VX700 chipset enables reduction of
mobile form factors by up to 40%. As the
first single chip implementation of its
kind for ultra mobile devices, the VIA VX700 continues VIA’s history of chipset
innovation and blazes a strong path for a new breed of digital companions.
By integrating the traditional chipset North Bridge and South Bridge into a single-chip
solution a number of advantages can be realized including:
Smaller form factors
Reduced power consumption
Less heat and easier cooling
Better performance

Making Your World Portable
Enabling Smaller Form Factors
The VIA VX700 is a highly compact single chip solution designed specifically for
today’s ultra mobile devices designed to fit comfortably into a pocket or handbag
enabling users to access and interact with their entire digital world wherever they go..
Combining the full functionality of a traditional North Bridge and South Bridge into a
Flip Chip BGA package measuring just 35mmx35mm, the VIA VX700 represents a
saving of more than 42% in silicon real estate, enabling for more simplified board
layouts and more room for additional onboard features. The host of leading digital
media, memory and connectivity technologies packed into the single-chip package of
the VIA VX700 also limits the need for additional add-on chips by system builders,
reducing complexity and cost.

Reduced Power Consumption
Ultra portability requires extreme levels of power efficiency, unprecedented
performance per watt and advanced power management to enable efficient battery
usage, and cool handling, while still retaining good performance. The VIA VX700
features VIA’s signature power efficiency technologies that are further
complemented by the VIA C7-M processor.
