See how you justify your behavour, by claiming you are saving the world from bad people that are trying to trick people into hurting their precious electronics.
Mike, im just trying to save the world from closed minded people. Some people think that their way is the only way, and when the only thing that matters is that they get their way, its ok to mistreat others to get your way, right?
There are no laws that say that I cant slowly (like it may take years slowly...) erode my leds, or show others how to slowly erode their LEDs. Sadly, I cannot guarantee that that I have any damage going on, or how much.
OK, I think i see how what current rating is so confusing, There are 3 primary choke points, all of which must be observed. It looks like there are many ratings (100ma, 200ma, 300ma, 400ma), but after examining the image, you can see that 400ma comes from 2VCCs, 300ma comes from the ports current restrictions combined (but I think you could do 350ma, if are clever), and the 100ma is from sinking on a single port. It sorta looks like several specifications for one thing, but its many separate things, and conditions that have some relationships to each other.
So, You can run 400ma through the chip, but through the io ports you shouldnt do more than 350, or 300, depending on how you source/sink, and you still have to be careful not to overload any one port, or more than 40ma through any single pin.
I found a website with both schematics:
on the TQFP:
Pins 2-6 are VCC or GND. There is additional AVCC and GND on pins 18,21. It would look like 600ma though the chip, but if the ports are the same, then im not sure what the benefit is.
