Yes, there are, and the industry players are pushing this as their main differentiator. However, for most projects I see, people don't care much. A better efficiency in a car is good, but a few microwatts can't compete with double the RAM in this context. Lots of electronics projects are not battery dependent, and engineers care more about reliability, development ease and speed and flexibility. I surely like the idea of not reimplementing a firmware ten years from now by just upgrading the micro controller, instead of dealing with a whole new set peripheral drivers.
