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
Measured with VIn = VDD.
4
All functional non-supply pins are internally clamped to VSS and VDD.
5
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.
6
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).
7
Maximum is highest voltage that POR is guaranteed.
