Introduction
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.
