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, "JD123"

I think I've seen that gadget somewhere else ... but Where ??? ( LOL !!! )

Welcome here , Gary !

PS : Those 12F629 are a Very Special Turkish batch ... like Sayzer's programmer ... ( a Special Turkish copy of the K149 from Kits'r us ... )

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?

AlainOkay, I have to admit... it could be worse.

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 ...
