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 –40 °C  T

 85 °C, or 3.0 V to 3.6 V and –40 °C  T

 85 °C, respectively. Typical parameters apply to 5 V and 3.3 V at 25 °C

and are for design guidance only.
