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

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... |

Maximum DC voltage listed is 6.0v ......... DC http://www.atmel.com/dyn/resources/prod_documents/doc1477.pdf 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. |
