The BD9591AMWV and BD9594AMWV system power management ICs supplies power to the main system blocks, including the CPU, IOH, clock IC and DDR2 memory. A complicated supply sequency controller is also built in, eliminating the need for a special power supply control IC while enabling configuration of an optimized system power supply and environment for the Intel® Atom™ E600 Series processor. |
