FreeScale has some 16-bit microcontrollers with built-in RAM, built-in
flash, built-in EEPROM, built in A/D converters, etc., and they sell
them in small quantities for around $10 each. I don't know anything
about building circuits for them or programming them. I just found
them on the web site after I started out looking for DSPs (which are
more like $30 each in quantities of 100s).
