New to 10F220

[Kamikaze47]

The 12F510 would be the cheapest that meets your requirements:

*edit*: as long as you dont need a lot of code space. The code space is 4 times that of the 10F220, but still limited.

My local supplier don't have the 12F510 in DIP-package, only in SMD.

The PIC12F629 is slightly more expensive, but in stock in DIP. ??

The 629 has no ADC !!!

Choose 12F675 ... or the 12F683 which is not really more expensive, but offers lots of interesting features and ... 2K program space.

BTW ... could have been an idea to tell us what you intend to do ... don't you think ???

Or even better, define cheaper. After all is a $2-3 part too much? Is there a budget amount in mind? Is board space an issue?

Lots of variables when considering a PIC.

Well, the 12F683 is about $2 and that's OK. The products will sell for around $80, hopefully.

Instead of small size, I could have stated 8DIP with the possibility to go to 8SOIC in the future.


I will probably be back very soon with more stupid questions about PIC12F683, but that will be a new thread!

Thanks for pointing me in the right direction.

My first project is very simple:
A 9 minute timer with a short blink every second to show that it's counting and a low battery indicator. I need 1 x ADC and 2 x output (LEDs) for this project.

Next project is almost as simple:
A temperature regulator with 3 different levels that will be exucuted in a preset sequence, for example start-go to 50C-wait for x minutes-go to 28C-wait z minutes-got to 32C.
A bicolour LED shall indicate the different steps.
A potentiometer shall be able to adjust the temperatures +/- 2C.
I need 2 x ADC and 3 x output (2xLED + TRIAC) for this.

Ok ...

12F675 is nice ... but a bit limited if some PWM or Compare jobs used ...

you can start with the 12F683 ( 8 pins with the more peripherals / SMD available - 12F1822 nice too ( brand new chip ! ), if you do not intend to drive a LCD.

16F886 ( 28p ) or 887 ( 40p ) if you need more pins .... cheap and numerous peripherals.

Got to start somewhere....
My test program with two blinking LEDs worked right away with the 12F683, so I think I will use that for now.
Both my projects will hopefully be products, but probably not in large numbers.

I'm trying to educate myself using some educational materials that include a LAB X-1 and PIC16F877A, a bit overkill for my needs.


I have been an electronic designer for about 30 years, but I realize that many times a PIC is a better/smaller solution than OP-amps, timers and counters.
