High performance-low power Intel Atom processors are being designed into a wide range of embedded applications that would not be practicable with mobile, desktop or server CPUs. While many Intel Atom processor power supply requirements have a lineage that trace back to more conventional mobile and desktop processors, there are differences due not only to the reduced operating current, but also the high levels of integration. This paper explains what is required to deliver power to embedded platforms with Intel Atom processors. The significance of the Intel mobile voltage position specification is explained as well as the roles of the system management controller and power management integrated circuits.
