The VIA PN266T is an efficient, cost-effective, flexible chipset solution for mobile systems based on the Intel® Pentium® III Processor-M and VIA C3® mobile processors, across a full spectrum of applications.
With up to 2.1 GB/s of memory bandwidth for up to 4GB of DDR266 SDRAM, a 64-bit DDR 200/266 or PC100/133 SDRAM memory controller, and a 133 MHZ front side bus, the PN266T offers efficient system performance. The VIA PN266T also integrates the S3 Graphics ProSavage8™ 2D/3D engine, with internal AGP 8X bandwidth and DVD Motion Compensation optimized for use with the Microsoft Windows® XP operating system. Shared Memory Architecture (SMA) enables the PN266T to utilize the system memory for frame buffer and texture memory on a 128-bit internal data path doubled. In addition, employing low voltage DDR266 SDRAM with Intel® Speedstep™ Technology lowers system power consumption extends battery life and usability.
The VIA PN266T also makes use of VIA’s V-Link Hub Architecture, which provides a dedicated 266MB/s bus between the north and south bridges. Paired with any of the VIA V-MAP 8233 Series South Bridges, the VIA PN266T includes integrated 2 Channel AC’97 Audio, integrated MC’97 Modem, and support for ATA 33/66/100 and 4 or more USB ports. Options also include an integrated 3Com® networking MAC.
VIA PN266T Benefits
Low Power Consumption: DDR Memory operates at only 2.5V, offering low power consumption. The VIA PN266T is also fully compliant with Intel SpeedStep™ technology, realizing the benefits of dynamic power management and extending battery life even further.
Smooth DVD Playback and Gameplay: S3 Graphics ProSavage8 2D/3D technology with equivalent AGP 8X bandwidth and DVD motion compensation enables quality in key applications like DVD playback, along with smooth 3D game play.
VIA Stability and Reliability: VIA Chipset Platforms offer a balance of reliability and flexibility derived from using proven, modular components and evolutionary design principles.
