    Question 12f629

    It looks like I'm going to be using a 12F629 for an application.

    Any warnings/surprises/secrets and/or obscure aspects I should be aware of?

    Hi Russ,

    I have been using the 675 quite a bit lately and getting used to GPIO.X instead of PORT?.X is my only problem.

    We are using thousands of F629 in a month.

    The only issue we have is with the chip's eeprom. Most of the time, the eeprom is not good.
    So, we return lots of them; and this is time consuming.

    When we use F675, we do not get any bad eeprom issue.

    So, if you have lots of "write" routines in your application, I would say, go with F675.

    F675 is more expensive then F629 ( for us it is; for some other is does not matter).

    Be sure to turn off the analog comparators if you don't want them. Default has them turned on.

    sayzer, that's odd. I don't use thousands a month, but I do use hundreds a month. I use the eeprom area quite aggressively and so far (knock on wood) I have yet to find an eeprom issue with the 12F629's. This is what I make and sell: http://www.york-electronics.com/

    Hi Alain,

    Yep, I'm not know for being 'under cover' for very long.

    I wish I was named JD... who in their right mind thinks of "Gary" when they name their kids?

    Thumbs up

    Thanks for the information, folks!

    It looks like I need a single analog port now, so I'll probably graduate to the 675.

    Hi, Russ

    If your Analog measurements are ... not so precise, or slow ...comparators AND the trimmable voltage ref , or the RCTime function can do it ...

    Without any ADCs ...
