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
