Is 7-volts too much for a 5-volt requirement?

<< < (2/2)

ChadTower:

If I recognize that chip properly, it's just an eeprom.  No voltage changing whatsoever.

Havok:
Why can't you pull 5v from the computer power supply? I would think that is the best solution. Both the Ipac and Keywiz\GPWiz have a 5v tap for just this thing. Worse case - buy a universal adapter for $10 and wire that up...

ATMEL is all about microcontrollers now... Judging by the fact that its the only chip there, thats what I'd assume it is.

Yes, it is a microcontroller.  Feeding it 7V will not work.

Maximum DC voltage listed is 6.0v ......... DC

As already mentioned....
Use the 5.0v DC from a PC power supply if this is indeed for a MAME project or something similar that is using a PC.
