In a drone, how much the controllers eat is straight up irrelevant. Because you already have to keep 20A worth of motors powered or die trying. You aren't going to make a dent in your power problems by going from 40mA to 1mA on the flight controller MCU.

> Lots and lots of useful MCUs that are out there in the real world don't include these functions on-die. That's OK, isn't it?

No. It's embedded, and chips live and die by integration. You either get really good at being an easy to develop general purpose jack of all trades solution, or you get into a lucrative niche and design everything for the niche.

This appears to do neither. It's a specialized piece, but it's not specialized enough. It suggests some very specific applications, but doesn't deliver on being suited to them. Tech demo material.
