Does anyone know the difference between 16F628-20/P-ND and
16F628-20I/P-ND?  One with the 'I', the other one without it.  I saw
this in Digikey website.

I am a little confused because the one with the 'I' is a little more
expensive than the other, and I can't seem to find any difference
whatsoever in the description of the 2 chips.  I have checked microchip
website and the spec sheet, and I can't find anything.

In the spec sheet, it says that there are 2 types: 16F and 16LF (where
the LF version is the one that'll work at lower supply voltage).  But I
don't think this is it though!

Please enlighten me if anyone knows what the 'I' stands for.  Thank you
very much!
