What is your patent number? What is the temperature coefficient over the temperature range?

When was this product launched? Looks like these two are the first set of products launched by this company? Might be worth waiting for a while before putting this into an industrial embedded e;ectronics system?

Wonderful chip. As mentioned earlier, can they integrate energy harvesting device to dispense with battery and its its problems.

Ambiq is actually a spin-off from the University of Michigan, though you are right that low voltage circuit design is a key area of expertise and IP at Ambiq. Ambiq's IP was developed by a group of leading low power researchers over the last 8 years and is wide ranging. If you are interested in learning more about the company's technology, please visit http://ambiqmicro.com/technology. Please also feel free to send any unanswered questions to info@ambiqmicro.com. -Scott Hanson, CEO/Founder at Ambiq

If I remember correctly, this is the spinoff from UIUC group working on subthreshold circuits. Any circuit with modifications to make sure, it works in the sub threshold region can be patentable. Meets the patentability criteria on novelty and non obviousness.

This will put the RTCs from the list of power hungry interface's list in the embedded systems, and designers will be able to make use of it efficiently, it will also help a lot in biomedical applications of embedded systems.

These can be powered from our wrist using a wrist band electrodes. we can think of quite a new set of applications soon.

Interesting effort - 15nA. Good one

They seem to claim to have patented the RC oscillator, and also using a N channel MOSFET as a Power Switch ? Amazing. Underlines why Patent reform is LONG overdue. That aside, the numbers are impressive, but it seems they consider waving the patent banner, more important than telling anyone the price.

Nice set of features for only 15nA. Can be used with energy harvesting devices to create a no-power system with a good feature set.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
