Hopefully this is the last time I use Google Gropes. You guys are right. Yeesh. Sorry about this.
I have used PIC chips for well over a decade, and in particular, have developed circuits using the PIC16C773 due to the 12-bit ADC. Everything would be rosy with the '773, except that I fried my two windowed chips, they are no longer stocked by DigiKey or Mouser, and it just seems like I could modernize a bit with an MCU that supports, among other things:
- 12-bit ADC
- Serial port
- EEPROM or Flash, instead of EPROM / OTP
- Low pin count packages that a geezer can solder -- does not have to be DIP necessarily
- Free software tools, possibly even C compiler
- Relatively painless programmer hardware
Another option would be to use one of the flash-based PIC chips and switch to an outboard ADC, if the collective wisdom favored such a route.
Thanks in advance for letting me use GG one last time, and for any wisdom you are willing to share.
