PIC current specs?

Yes, I see about the max Port current limits. Now about the max pin current again, <25mA continuous is reliable if other max's are adhered to? Any experience with sourcing this?

Nope... can't say I've ever tested how long an output can sink or source current continuously. But then.... what does continuously really mean? Hours, days, years? I did dig through the same data sheet again, and didn't see any charts relating to this. Sounds like what you want is some endurance test data. Maybe one of the 'ol pros can give you some information based on some of their applications. Sorry I could'nt be any more help.

My prototype LED stair lighting system direct drives LEDs at 20mA. The lights pull 160mA directly from the PIC and I have had no problems with it...

What is the Imax allow port pin sink/source for the PIC you are using? Is it 20 or 25mA?

Thanks

I am using a 16f628 it can sink or source 25mA per pin, there is a MAX of 200mA for both ports combined.

Good info. Post back here if you find the PIC ever getting hot or other related probs.

Good info. Post back here if you find the PIC ever getting hot or other related probs, and I will do the same. I am sourcing 19mA and about 50 mA total port.
