    I’m using a low power PIC in my project, specifically the PIC16LF1786, which has a VDD of 3.3V. What I’ve been wondering is, do the I/O voltage levels match VDD? For instance is a logic level HIGH 3.3V? or 5V?

     

    I suppose I could supply different voltages and see what triggers it… the data sheet isn’t a big help in this situation since its for both the low and high power versions.

    Hi,

    If VDD is 3.3V how come it could give 5V at IO pins?

    By using a charge pump…

    Don’t think this microcontroller has charge pump connected to I/O ports, however they are used for flash memory write/erase.

    It is clearly written in the datasheet under “30.4 DC Characteristics: PIC16(L)F1784/6/7-I/E”

    that the Maximum Output low voltage will be 0.6V and Minimum Output high voltage will be VDD – 0.7V.
