I think I halted, snoozed and slept, but never deep slept -- trying to be efficient, conserve energy. Slide 16 is a good summary chart, good way to review. Some applications put a heavy load on you and have a lot of repetition or take a lot of processing time. Good examples and resource references tied the presentation together well.
erichard- I find that battery back-up power is typically used when the rest of the MCU is running off of a mains power supply. If the power the MCU is using is important to know, then you are correct that the battery power must be included. Luckily battery back-up power is typically in the nA range (for most of the recent Low Power MCUs).
richwillaims- Yes the ferro RAM is a very interesting development. I'm expecting more MCUs to move in this direction. This technology can offer the best of both Flash and SRAM and ferro RAM has some really robust environmental characteristics too!
mharkins- You are correct. With some data flash implementations (most of them actually) there are voltage limits needed to write to Data Flash. If there is an on-chip regulator this can also make a difference.
The streaming audio player will appear on this web page when the show starts at 2pm eastern today. Note however that some companies block live audio streams. If when the show starts you don't hear any audio, try refreshing your browser.
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.
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.
