I see a definite advantahe of 5V Vcc capable chips for USB powered apps, but what else but ludditeism requires 5V Vcc I've done a couple of USB designs, and none of the logic requires 5V. The bus supply is always regulated down to 3.3V. Some (most?) USB micros these days have an onboard regulator which supplies 3.3V from the bus supply. -a |
