I have using this chip (MC68HC705B16CFN) for well over 10 years. I'm having a lot of trouble finding these chips. I'd like to update to a newer chip that can accept the program file that is being used for the MC68HC705B16CFN. It's been many years since I have had to deal with programming, so I would not like to start over with the programming. I've looked around to try to find a suitable replacement, but have come up short. My application uses the A/D input on PD3. I believe this is why I've been coming up short. Is there any hope for me to find such a replacement?
