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).
8
Maximum is highest voltage that POR is guaranteed.
9
Run at 1 MHz bus frequency
10 Low voltage detection and warning limits measured at 1 MHz bus frequency.
