This concept of a universal memory is nothing but wonderful, although it does come at a price. I'd like to see ARM mcu's like Cortex-M coming with some NVM options (FRAM, MRAM etc). Who is going to be the first manufacturer to introduce it?
It has been a long time coming, I am sure many engineers will specify FRAM MCUs for the combination of sweet features. I would like to see more architectures supported though, the 430 is not the nicest, but it majors on low power which is what matters in many apps.
I have long been using external FRAM for state non-volatility and it makes everything so simple, there is time to update it with a checksum at every user event, so when you power up, everything is just the way you want it, no low power drain when off.
Great to have it inside the MCU although is it for free? I suspect not, but it will be cheap compared to an ext chip.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
