No question it's a pretty powerful M4 in a tiny package, but stock of 25 seems like a teaser given the part was released Jan 2018.
If you're Maxim and trying to get a leg into the MCU market, this seems a bit low energy?
I have no idea how the peripherals are, for complexity and I then ran into:
"...Alas, you can't get a datasheet without an NDA"
http://www.ganssle.com/tem/tem358.htmlIs this true, the tiny little M4 needs an NDA signed to get the datasheet?
