Looking for an 8 bit device that has more than 9+1 internal pullups (space constraints).

Seems PORTB + MCLR is the rule for programmable pullups. I've looked through a slug of datasheets and found nothing. Just wondering if someone happens to know of one I missed.

Depends on which 'family'. Some of the "enhanced mid-range" devices have more pull-ups. For example, the 20-pin 16F1829 has pull-ups for all 18 I/O pins... the 28-pin 16F1788 has pull-ups for all 25 I/O pins... and the 40-pin 16F1789 has pull-ups for all 36 I/O pins...

MMcLaren: Awesome, the PIC16F1789 is just the ticket. May I ask how you found that?

I'm with you spinnaker, I was expecting to see this in the parametric search.
