The Intel® Atom™ Processor E6xx Series is the next-generation Intel® architecture (IA) CPU for the small form factor ultra low power embedded segments based on a new architecture partitioning. The new architecture partitioning integrates the 3D graphics engine, memory controller and other blocks with the IA CPU core.

The processor departs from the proprietary chipset interfaces used by other IA CPUs to an open-standard, industry-proven PCI Express* v1.0 interface. This allows it to be paired with customer-defined IOH, ASIC, FPGA and off-the-shelf discrete components. This provides utmost flexibility in IO solutions. This is important for deeply embedded applications, in which IOs differ from one application to another, unlike traditional PClike applications.
