Intel® Centrino™ mobile technology is Intel's new technology designed specifically for mobile computing with integrated wireless LAN capability and breakthrough mobile performance. It also enables extended battery life and sleek, easy-to-carry notebook PCs.† This is Intel's first integrated computing technology designed from the ground up for wireless notebook PCs. Intel Centrino mobile technology supports some of the leading wireless security hardware, and software††, as well as with leading, access-point providers to allow users to stay connected and productive on the go†—for a truly mobile lifestyle.
With Intel Centrino mobile technology, three components work together to enable outstanding mobile performance, extended battery life and integrated wireless LAN capability in thinner and lighter notebooks. These components include the Intel® Pentium® M processor, the Intel® 855 Chipset Family and the Intel® PRO/Wireless 2100 network connection.
Intel® Pentium® M processor New micro architecture including power optimized 400 MHz processor system bus, Micro-Ops Fusion and Dedicated Stack Manager for faster execution of instructions at lower power. And advanced instruction prediction to reduce re-dos for increased performance.
Support for Enhanced Intel SpeedStep® technology w/ multiple voltage & frequency operating points, enabling a better match of performance to application demand
Support for Intel® Mobile Voltage Positioning, which dynamically lowers voltage based on processor activity to lower thermal design power enabling smaller notebooks.
1MB power managed L2 cache increasing system performance
Intel® 855 Chipset Family
Support for up to 2 GB of DDR 333/266/200 memory (DDR 333 available on Intel® 855PM chipset only) enables higher performance and flexibility
USB 2.0 support, for 40x max data transfer rate and is backward compatible to support USB 1.0 devices
Optional integrated graphics solution with Intel® Extreme Graphics 2 technology which delivers realistic 3D graphics with sharp images, and enables balanced memory usage between graphics and system for optimal performance
Intel® PRO/Wireless 2100 network connection
Integrated 802.11b Wi-Fi CERTIFIED* wireless LAN capability to connect to Wi-Fi CERTIFIED* access points
Industry standard wireless LAN security support is available (such as 802.1X, WEP, WPA††).
Intel® Intelligent Scanning Technology reduces power by controlling the frequency of scanning for access points
Cisco Compatible* Extensions (such as LEAP and CKIP) support is available††
