The Intel® PXA270 processor (PXA270 processor) provides industry-leading multimedia
performance, low-power capabilities, rich peripheral integration and second generation memory
stacking. Designed from the ground up for wireless clients, it incorporates the latest Intel advances
in mobile technology over its predecessor, the Intel® PXA255 processor. These same attributes
and features also make the PXA270 processor ideal for embedded applications. The PXA270
processor redefines scalability by operating from 104 MHz up to 624 MHz, providing enough
performance for the most demanding mobile applications.
The PXA270 processor is the first Intel processor to include Intel® Wireless MMX? technology,
enabling high-performance, low-power multimedia acceleration with a general-purpose instruction
set. 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.
The PXA270 processor is offered in two packages: 13x13 mm VFBGA and 23x23 mm PBGA.
