Not if meets the right balance of cost and performance. If it adds too much cost to the BOM then only the designs trying to squeeze every last nanowatt will want the part. On the other hand, if they get the part under a dime in volume then I can use a cheaper, power guzzling micro and spend the dime on their part. It's another performance/cost trade off.
It definitely seems like Anagear is on to something here with its preservation of power it manages by taking power management out of the microcontroller. It seems a fairly simplistic idea and will be interesting to see if this takes off. I wonder if designers might balk at making this change to the time-worn design.
Very true, so many designs simply need to wake up every second or so to make a measurement and that clock circuitry usually takes a few microamps. Microcontroller vendors have gotten better at providing a low current wake-up but aren't really there yet.
ZiLOG has a pretty nice watchdog circuit in their Encore parts that can do it with less than a microamp.
Engineers at Fuel Cell Energy have found a way to take advantage of a side reaction, unique to their carbonate fuel cell that has nothing to do with energy production, as a potential, cost-effective solution to capturing carbon from fossil fuel power plants.
To get to a trillion sensors in the IoT that we all look forward to, there are many challenges to commercialization that still remain, including interoperability, the lack of standards, and the issue of security, to name a few.
This is part one of an article discussing the University of Washington’s nationally ranked FSAE electric car (eCar) and combustible car (cCar). Stay tuned for part two, tomorrow, which will discuss the four unique PCBs used in both the eCar and cCars.
