Cheap Microcontrollers

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?

This makes things easier for the LEDs, because you have to drive them with 3x the current, or more, for same brightness as steady state, and the 12750Hz higher frequency means a pulse duration of only 78us at this elevated instantaneous power dissipation versus 3.3ms with the 300Hz. ...
