If it does what you want, yes - but does it?

I guess you write in C or the like? It looks too constrained for MMBasic, for example.

Oddly that article doesn't seem to say what the instruction set and tool chain are, though maybe I missed it. (Hunting through the PDF does not appeal.)

... or assembler . The instruction set will be common across all the MAXQ20 cores a bit like MIPS. https://pdfserv.maximintegrated.com/en/ej/MER_7.pdf

You'd never get MMBasic in there and I thought no UART was a bad move - easy to do in software but no Rx interrupt is a pain... SPI is easy to do in software and I2C (which can be a sod) is there.

But, it is a new uC so good to know what is out there. I like maxim too. They have always produced useful chips. Honestly, I can't see myself rushing to get samples. I have got to a place where a MM handles pretty much any task (and with '170s at sub$5 there is no $$$ incentive to go small/assembler). I have heaps of basic PICs still for tiddly solutions. I am in a pretty good place, so why rock the boat? I am such a luddite

Yes, my thoughts too. I was a little surprised there was no UART, as lots and lots of things use basic serial. But then again, lots and lots of things use I2C or SPI too!

That made me think of the B/W Maximite - Geoff's first Micromite creation, that was featured in Silicon Chip. I was instantly drawn to that unit, but a little disappointed that it did not have any serial support at all. This was right back at the very start. Geoff soon released a new version of the firmware that included a bit-banged serial, and that was immediately put to use.

Smoke makes things work. When the smoke gets out, it stops!
