Direct replacement for 16F688

[Christopher4187]

Hi,

I have read through both datasheets and I believe that a 16F505 can be a direct replacement for a 16F688. I am using a 16F688 and I do not need any analog inputs, which is why I am looking at a 16F505. It looks like you can only run the 505 at 4MHz but for my application is does not matter. Can someone confirm my thoughts?

Thanks,

Chris

You read the datasheet well. Is only for 4 MHz. max. what the datasheet says!

Hi, mat

12F508,509 and 16F505 have only a 2 level stack ... and a special addressing scheme ... " so little" things to verify ...

Worth a close look to the Datasheet ....

Thanks Alain, but he gave so little info about his application, only he read well about the 4 MHz and no analog inputs.

I only need digital inputs/outputs, no requirement for a fast oscillator and no analog inputs. The footprint MUST be the same as the 16F688 and that is why I think the 16F505 will work the best.

Christopher4187, Why do you need a replacement?
