1 Typical values are measured at 25
C. Characterized, not tested
2 Measured with VIn = VDD or VSS.
3 Measured with VIn = VSS.
4 Measured with VIn = VDD.
5 All functional non-supply pins, except for PTC6 are internally clamped to V
SS 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.
7 Power supply must maintain regulation within operating V
DD range during instantaneous and operating maximum current
conditions. If the 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 that external VDD load will shunt current greater than maximum
injection current. This will be the greatest risk when the MCU is not consuming power. For instance, if no system clock is
present, or if clock rate is very low (which would reduce overall power consumption).
