content: How about a M4 MCU with FPU in under 4 square mm?https://datasheets.maximintegrated.com/en/ds/MAX32660.pdfThe mind boggles at possibilities....

content: 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?

content: Maxim site search for'max32660'returns zero hitsThanks for the link, I wanted to see how Maxim design and document the peripherals.It looked clear, but a bit weird (brief) User Guide at 195 pages, whereas ARM MCU's tech manuals are typically 1,000+ pages.This part dethrones Freescale's KL03 M0+ "world's smallest ARM microcontroller".I wondered what you can do with only 14 I/O yet utilize 96KB SRAM, 256KB FLASH, 96MHz.https://hackaday.io/project/160283-max32660-motion-co-processor

content: The skimpiness of the ref man probably has to do with the fact that it only has basic I/O functions. Nothing fancy like USB, CRYPTO etc. I just ordered a devkit and will be writing some test programs. We will see how well the header files look and how well the Segger JLink works with it. It's pretty exciting with the large amount of flash AND especially SRAM!

content: the Freescale KL03 I recall it was intended for swallowable medical projects so the "96KB SRAM, 256KB FLASH" is intended to capture all the data before it ermm, passes out the other side.
