ARM Releases "World's Most Efficient Processor"
ARM today announced a new low-power processor, the Cortex-M0+, which the company claims is "the world's most energy-efficient microprocessor".

According to the IP provider, the chip is designed to be used in home appliances, white goods, medical monitoring, metering, lighting and power and motor control devices to deliver an "ultra low-power" of 9µA/MHz on a 90nm LP process.
The Cortex-M0+ fits into a new product trend that is generally referred to as the "Internet of Things", which describes an environment in which simple devices are wirelessly connected to each other and can provide communication, management and maintenance capability. ARM imagines its new processors to be used in applications ranging from "sensors to wirelessly analyze the performance and control of domestic or industrial buildings, to battery-operated body sensors wirelessly connected to health monitoring equipment."
ARM said that the new 32-bit chip, which builds on the platform of the Cortex-M0, consumes only one third of 8-bit and 16-bit processors that are used in the application field targeted by the processor. Developers can use the ARM Keil MDK to compile and debug 32-bit applications for the chip. According to ARM, early licensees of the Cortex-M0+ chip include Freescale and NXP.
Since when is Amps a measure of energy? Energy is measured in JULES. If you're gonna give amps, at least give voltage too.
I love when people make mistakes while angrily pointing out others' mistakes. I think you meant "joules".
true but considering it uses a 1/3 of the power of a 8bit chip is sweet.

makes you wonder what a 22nm chip like this will be like. Maybe it will be able to run on less than 0.1w of power.
Well, by strict definition, everything with a chip has an OS... And well... Samsung already has several appliances with WiFi
Cheers!
I'd bet $10 your microwave is running unix right now.
90nm probably costs less to make?

I have to disagree. It all depends on the appliance. For example, notifications from items like shared washing machines and laundry dryers would kick a** in an apartment setting especially. *Bing* Your dryer is done... *Bing* The dryer is now free *Bing* The rinse cycle has started... etc etc etc.

I think something's missing ... consumers only one third the power of 8-bit ...

1) We need an edit option
2) I need to turn off auto-correct
It takes nine microwatts per megahertz, I think it would be under your 0.1W figure most of the time.
As for 22nm, maybe with a die this small they'd have problems with power gating and whatnot to stop leakage from a smaller process, just a guess. Otherwise I can't think why something they want to draw the least possible power would be on such an old process, even 65nm would have higher yields and still be very attainable.
Even a dumbphone (err, featurephone) would have a more powerful processor than this, its not made for smartphones and I doubt it could run a modern OS, this is for appliances that just need to send and receive simple information like power draw of other appliances.
I sure hope they put a "Mute" button
