1 Maximum is highest voltage that POR is guaranteed.

2 RAM will retain data down to POR voltage. RAM data not guaranteed to be valid following a POR.

3 This parameter is characterized and not tested on each device.

4 Measurement condition for pull resistors: VIn = VSS for pullup and VIn = VDD for pulldown.

5 All functional non-supply pins are internally clamped to VSS and VDD.

6 Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate

resistance values for positive and negative clamp voltages, then use the larger of the two values.
