PIC18F46K22 POWER AND GROUND CONNECTIONS

#1 Post by pumper » 22 Jun 2012 19:38

Do both VDD pin 11 and pin 32 as well as gnd pin 12 and 31 have to be connected to pwr and gnd? Or are these connected internally.

Can't find anything in the data sheet that says.

You can try - that's part of the fun.

In generally, you want them all to be connected to power / ground, respectively. Having said that, I have yet to find a pic where you have to connect them all to get it to work.

This is typically implied.
