But maybe it is worth doing a sub-dollar MCU selection table,
there are many such chips, very few are known outside of China.
Yes, but as far as I'm interested, only Cortex M3/0/0+ would make it to this table. I know, that there is PIC10 or MSP430 which is cheaper than the cheapest M0, but I also have to keep in mind, that they offer so much more, that I never would consider a PIC10. And I'm well avare, that there are a lot 8051 based, or even 4 bit MCU, which are cheaper than a not gate from Texas instruments, but for some magical reason, I would like to buy the chips. And download the datasheets. And have programming cables, and ICPs, with proper documentation. ARM does that, and to top this, you can give the board to an "out of university" programmer to make the code.
Not to mention, NXP and ST are EU companies.
Yesterday, ST announced the STM32F030 series.
Um. You mean like back in July? "32 bits for 32 cents" ?
I dont know, I got the mail from them yesterday, "Microcontroller news from STMicroelectronics November 2013". So far no stocks.
I made the question, because the battle is far from over. We are still waiting for Atmel, the D20 is positioned above these, and the name also suggests, that something is coming below that.
