Hello there, I'm looking for a very cheap microcontroller indeed. Price
point is under 0.35 USD, quantities of 50-100k for first production runs.
Application is an RGB LED controller that accepts color information over
asynchronous serial communication. I crammed that in an attiny11 pretty
easily, but Atmel is discontinuing that model and replacing it with the
2-3X as expensive attiny13! While it's nice that the attiny13 has alot of
fun peripherals, all I really need is a moderately fast (2-4MIPS) cpu core
and a handful of I/O. I've been trying to get some quotes from the major
asian companies, Winbond, Sonix, Elan, but getting a response from them is
like e-mailing with a fencepost. It's like these companies don't even
want
to make a sale. So now I find myself turning to the online community for
advice and suggestions.

Also, is it possible to get manufacturers to supply dies for chip on board
manufacturing? I bought some cool RGB fading leds that incorporate some
sort of controller into the 5mm LED package, and it would be cool if we
could do a similar thing.

Thanks for any assistance you can provide?


Talk to Atmel direct..... 100K is big enough to call the shots....
