Power Management IC Simplifies ACPI Implementation (HIP6501AEVAL1)

0 The Advanced Configuration and Power Interface specification (ACPI; [1]), written by a consortium representing Intel, Microsoft and Toshiba, attempts to evolve the current collection of power management methods and configuration interfaces into a well-specified and unified power management and configuration mechanism. The key objective in the ACPI specification is to transfer all control of power management and configuration functions to the operating system, thus enabling Operating System Directed Power Management (OSPM). ACPI-compliant systems will benefit from a robust interface for configuring motherboard devices, a versatile power management interface enabling a wide variety of solutions with full operating-system support, and not lastly, a realm of new, intelligent possibilities added to the already broad span of PC uses. The HIP6501A is the first Intersil IC to be used in conjunction with a second chip to provide a complete ACPI-sanctioned motherboard power regulation solution. The HIP6501A/HIP6021 chip sets produce the processor core, GTL bus, memory controller hub, and clock chip voltages, as well as the SDRAM memory, 3.3V and 5V dual voltage planes [2, 3] necessary for a complete PIII-Whitney system implementation.
