#2 The chip is so low power that it can be powered off energy
capture from the body, as Andreas Eieland, Atmel's Director
of Product Marketing for low-power products, demonstrated at
CES earlier this year.

#3I think that this just killed the one of the triumph card of PIC micro-controllers.
Seriously, Microchip uC have now any interesting thing apart of a lot of embed I/O hardware inside ? ARM based uCs now are cheap, low powered and have far better IDEs and compilers...

#4Now we only need batteries that don't self-discharge within decades.

#5The chip is so low power that it can be powered off energy capture from the body, as Andreas Eieland, Atmel's Director of Product Marketing for low-power products, demonstrated at CES earlier this year. The human body generates more bio-electricity than a 120v battery, and over 25,000 BTUs of body heat. Combined with the Atmel SAM L21 32-bit ARM MCU, the machines had found... all the energy they would ever need.
Valid reference. Well, I think it is, might not fulfil Wikipedia guidelines though.

This is likely intended to be use with batteries that can recharge from very low-energy sources, e.g. energy captured from the body. It has very small energy consumption in sleep mode, so the battery can charge between wake cycles. 200 nA is, indeed, very low.

british BTU or american BTU? please use SI standard measures for those who don't happen to live in America :-)

The strongest selling point for PIC is always the quality of the I/O hardware and the attention to the low-volume market. The CPU core is just something that you need to deal with.
ATMEL is always great presenting fabulous MCU than sometimes takes forever to reach the low-volume markets.
Lead time is always an important parameter to consider when choosing a new MCU for a low-volume project :-)
I used to start new projects looking on digikey website more than anything.

I think they are referring to kinetic energy from body movement, although tapping into heat loss and other wasted energy sources would be awesome too.

#10Ah! But this chip only has a sub-uA sleep mode. So it will have the said decades battery life if it sleeps most of the time, which might be true in the cases of some kind of IoT application, but not if it's actually running often.
