Quark, Low Power? I think not

In what universe is 35mW low power? Even if the chip was running at 1.8V that would still equate to 18mA of active current draw! This is an order of magnitude higher than most world class low power MCUs.

Typical consumption of leading ARM M4 MCUs(40~65nm) hover around 50uA/MHz which will put them at a significant advantage power wise. Even older node M4s average around 280uA/MHz which is still 3x lower at the same clock speed. Granted the x86 may offer other advantages(none I can think of) but I don't believe Intel is serious about wooing this class of embedded customers if they think they can get away with a 180nm process. 

Anyone have any real hands-on with developing applications for the Quark? Is the library/compiler/development environment something special? Anything even remotely comparable to the massive amount of freely available info for ARM?

Chip temp limit must be in degrees C

Great article, as usual, from Rick Merritt.

A minor correction:

"The E3900 is sampling now in versions supporting operating temperatures up to 85 degrees F with production early next year. Versions supporting operation up to 110 degrees F for automotive will arrive by June."

 

85 degrees F and 110 degrees F don't make sense.  It must be 85 degrees C and

110 degrees C.   

 

Thanks,

Tom
