12F509 vs 12C509

[T.Jackson]

I think the main difference between the C & the F is that the F uses flash memory, making it re-programmable. The C series is program once only. Perhaps I'm wrong, trying to recall some readings from sometime ago.

Can someone help, i would like to start a pll synthesizer project, frequency must range from 88.5-108mhz steep of 50k, a pic 12f629 controller and a mc145170 pll ic. This must be a single frequency. Some time back i remember a website call freddospage.nl had some pll with the pic12f629 but thay ware for saa1057 -tsa5511-tsa6057ic but not the mc145170 can you help me with the controller hexcode.

Nice thread hijack...NOT!

Seems I remember the 12C509 coming in both OTP (non-windowed) and UV-erase (windowed) versions back in the day.

But, no, I would think that code written for a 12C509 won't run on a 12F509 without minor changes.
