NHPXA270C5C520

NHPXA270C5C520 Description

The NHPXA270C5C520 processor is the first Intel processor to include Intel® Wireless MMX™ technology, enabling high-performance, low-power multimedia acceleration with a general-purpose instructionset. Intel® Quick Capture technology provides a flexible and powerful camera interface for capturing digital images and video. While performance is key in the PXA270 processor, power consumption is also a critical component. The new capabilities of Wireless Intel SpeedStep®technology set the standard for low-power consumption.
