ARM Ltd and National Semiconductor Corp. have released the PowerWise Interface (PWI) technology, jointly promoted as an open standard interface for system power management. The PWI specification defines a 2-wire serial interface connecting the integrated power controller of a SoC processor system with a PMIC (power management integrated circuit) voltage regulation system that enables system designers to dynamically adjust the supply and threshold voltages on digital processors.

PWI technology is expected to enable rapid deployment of advanced power management solutions in handheld electronic devices by providing an open, industry-wide standard for interconnects between digital processors and power management ICs.

Designers' dilemma of having to reduce the power consumption of digital processors while simultaneously maximizing battery life has led to the development of more advanced power management solutions that dynamically reduce power consumption based on the application software workload and environmental conditions. PWI technology is said to provide the hardware interconnect standard for universal deployment of such solutions.
