National Semiconductor Corp. of Santa Clara, CA, released the second-generation, digitally programmable LP5552 PowerWise energy management unit (EMU) and advanced power controller (APC2) intellectual property (IP) package for reducing power consumption in battery-powered handheld consumer products. Nationalís APC2 IP pairs with the LP5552 EMU to reduce the power consumption of high data-rate digital processors with frequency-scaling capability by up to 70 percent.
The APC2 is compatible with Intelligent Energy Manager frequency-scaling technology from ARM Ltd. The LP5552 and APC2 are compliant with the PowerWise Interface 2.0 open-industry standard introduced by National and ARM earlier this year.
The LP5552 enables a digital processor to adaptively adjust its supply voltage to the minimum level needed, greatly reducing its power consumption. The LP5552 includes two adaptive-supply-voltage buck regulators for the processor cores and five additional programmable regulators.
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. Iíve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
