Hi, all:- As the subject, what is the cheapest available micro with an on-board 10-bit A/D. I can't consider a "homemade" A/D for this application. (Expected volume in the range of 1-2K/month). The 16F870 is ideal in most other ways, but a little $$ and I don't need the EEPROM nor do I need FLASH. I'd also prefer an on-chip clock to save the cost of a resonator.
