1
Typical values are measured at 25
C. Characterized, not tested
2
As the supply voltage rises, the LVD circuit will hold the MCU in reset until the supply has risen above VLVDL.
3
Does not include analog module pins. Dedicated analog pins should not be pulled to VDD or VSS and should be left floating when not used
to reduce current leakage.
4
Measured with VIn = VDD.
5
All functional non-supply pins are internally clamped to VSS and VDD,except PTD1.
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 VDD 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).
