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. National’s 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.
There is currently much discussion around the term "platform," which may be preceded by the adjectives "mobile," "wearable," "medical," "healthcare," etc. However, regardless of the platform being discussed, they usually have one key aspect in common: They tend to be wireless. So, why is this one aspect so fairly universal? The answer is convenience.
Everyone has a MEMS story. For most of us it’s probably the airbag that saved our lives or the life of a loved one. Perhaps it’s the tire pressure sensor that alerted us about deflation before we were stranded alone on a dark muddy road.
Bioimimicry is not merely a helpful design tool -- it also encourages designers to think not only about how to solve design problems by imitating nature, but how to make the products, materials, and systems they design more ecologically sound and nature-friendly.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
