INTEL ON MONDAY ushered in the dawn of its X-Scale architecture for multimedia phones and advanced PDAs with the launch of two new X-Scale chips.

Designed for advanced PDAs, the PXA250 is available at speeds of 200MHz, 300MHz, and 400MHz. While designed for low power, the PXA250 offers a Turbo Mode for application acceleration and multimedia acceleration with Intel Media Processing technology. USB, 920Kbps Bluetooth wireless , and a 1.84MHz baseband interface are offered as communication interfaces, and an enhanced memory support 2.5 volt or 3.3 volt 16-bit or 32-bit memory. Targeted at simpler handheld devices, the PXA210 runs between 133MHz and 200MHz and offers variable power 16-bit memory.

Built to 0.18-micron architecture, the two new X-Scale chips use less than half the power of their predecessor, the SA-1110, when operating in run mode. Both chips are tuned for Java and run operating systems from Microsoft, Palm, Symbian, and Linux.
