It's amazing to see how many MCU manufacturers are developing low-power products, but it's clearly being done to meet the demands of the market. We saw a couple more at the recent Sensors Expo, and we'll be writing about those in the next few days.

N I guess 100uA/MHz is good enough for many products.

I agree, tekochip. A lot of companies are bragging about their low current draw these days, but 100 uA/MHz is really good, even among the today's proliferation of low-power products.

It's funny you mentioned the magnetic core memories, naperlou, because the old magnetic drum was the thing that came to mind for me when I first heard about this a few years back. Here's a trip down memory lane:

I've used FRAM in a few memory applications but I haven't used a FRAM micro yet.  When using FRAM you really have to approach a design differently because the memory behaves completely differently from what we're used to.  The first FRAM micros didn't really seem to take advantage of the low current capabilities of FRAM, so I'll definitely take a look at these parts to see what they can deliver.  100uA/MHz is a pretty attractive mark.

I looked up FRAM technology and according to the Wikipedia articel it was first proposed in a Master's thesis in 1952.  Wow, older than me!

This reminds me of the old magnetic core memories on mainframe computers.  It is interesting to see old concepts improved and used in new ways to achieve a goal.
