Notes:

1. All minimum and maximum values are guaranteed across the recommended operating conditions of supply voltage

and from –40 to +85 °C unless otherwise stated. All typical values apply at VDD = 3.3 V and 25 °C unless otherwise

stated.

2. 6.7 ns is typical for GPIO0 rise time.

3. Assuming VDD = 3.3 V, drive strength is specified at Voh (min) = 2.64 V and Vol(max) = 0.66 V at room temperature.

4. 2.4 ns is typical for GPIO0 fall time.
