I searched primarily for more RAM, but the 16Mhz internal oscillator is a
great bonus.  That eliminates a resonator I use on some apps where I needed
more than 8Mhz.  The F886 does not have 512 bytes of RAM (IIRC 368).  I just
looked up the 18F2620 and it does not come in 28-SSOP format, hence why it
did not come up in my search.  The 18F23K20 does seem like a good option,
but that too is relatively new, and I thought I'd ask about the 16F1936
first, as the extra code space will probably come in handy soon.

I usually buy PICs 1,000 pcs at a time nowadays, and standardizing has great
advantages.  For example, I recently did a short custom project which
required 60 pcs of a 16F630, but I modified the code for a 16F883 and now
don't have to worry about keeping spares of those in stock, etc.   Yes, I
still use other part numbers for other projects (example 16F917 for a
project that requires more I/O. and 12F629 on a project that fits in a
keyfob enclosure).

Cheers,
-Neil.
