ECIO28P at 3.3v?

Post by benh »

Is it possible to run a ECIO28P at 3.3 volts instead of 5v(using external power, not USB)?

Hello,

The datasheet says that 4.2V is the minimum voltage for the PIC to run at the 48MHz required for the USB communications. You could give it a go and it won't damage anything but as I say it will be out of tolerance for the predefined clock speed.
