DC Electrical Characteristics
DC GPIO Specifications
The following table lists guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to 5.25 V
and 0 °C < TA < 70 °C, or 3.15 V to 3.5 V and 0 °C < TA < 70 °C, respectively. Typical parameters apply to 5 V and 3.3 V at 25 °C and
are for design guidance only.
