AC General Purpose IO Specifications

The following tables list guaranteed maximum and minimum specifications for the voltage and temperature ranges: 3.0V to 3.6V

and 0°C <

< 70°C, or 2.4V to 3.0V and 0°C < T

< 70°C, respectively. Typical parameters apply to 3.3V, or 2.7V at 25°C and

are for design guidance only.
