Cool. What kinds of products are we talking about, what prices and what
As someone already noted, I think PIC and AVR are too expensive to use in
mass produced products (MSP430 has a price point which is more to my
liking). If you order a million you might get the price down to $0.5--$1 but
no less. Very few consumer products sell in such quantities. If you're
designing something that sells in the 10K-100K range, the price of the MCU
becomes a very significant part of the overall price ($3-$5).
