(2) Current into a device pin is defined as positive. Current out of device pins is defined as negative. Voltages are referenced to Ground unless otherwise specified. (3) Typical supply condition is VDDIO = 1.8V and VDD = VDDA = 3.0V, Maximum supply condition is VDDIO = VDD = VDDA = 3.3V for the IDD parameter.
