1 Typical values are based on characterization data at 25

°C unless otherwise stated.

2 Maximum is highest voltage that POR is guaranteed.

3 Measured with V

In = VSS.

4 Measured with V

In = VDD.

5 Power supply must maintain regulation within operating V

DD range during instantaneous and operating

maximum current conditions. If positive injection current (VIn > VDD) is greater than IDD, the injection current may

flow out of VDD and could result in external power supply going out of regulation. Ensure external VDD load will

shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not

consuming power. Examples are: if no system clock is present, or if clock rate is very low (which would reduce

overall power consumption).

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

7 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.

8 The RESET pin does not have a clamp diode to VDD. Do not drive this pin above VDD.
