Are You Satisfied with the Specs of the Present Generation of Low-Power Devices?

Low-power, ultra-low-power, nano-power -- terms we see in just about every new product introduction, data sheet, or specifications. Clearly, the low-power spec of semiconductor devices today is critical as portable, battery-powered devices are seeing a high level of growth; this trend is expected to continue. But where are we at now? Is the current generation of low-power devices meeting your needs or do you need even lower power consumption to meet the needs of your designs? If so, what level of low-power consumption would you like to see?

  • Me personally started with electronics when AtMEGA32 was the king of the day and ARM had just started off. Coming form that background to ULP STM32's and Cortex M0+'s and MSP430's .. .. ..

    There has been a huge improvement in the power domain. Unfortunately nowadays when I meet college UG and ask them that have a completely different opinion as that start with the ULP devices and then look further.

     

    This poll really took me down the memory lane. image

  • The power has to be low enough to be run by harvested energy. I think we are getting near, but not always there. Thanks for the poll.

  • There will always be a need for lower power and even where it is not absolutely needed, it is generally nice to have.

    With today's technology it should be possible to have a cell phone last between 4 and 10 times longer on a charge and there is certainly demand for that type of performance. Maybe displays spend most of their time as ultra low-power black and white displays. Maybe the processor and other circuitry use sub-threshold voltages. Maybe battery energy is doubled or quadrupled. Maybe (5G) cell towers are so close together, radio power can be cut dramatically. How much of a premium would you pay for lower power phones or fanless computers?
