1 Typical values are measured at 25
C. Characterized, not tested.
2 The specified resistor value is the actual value internal to the device. The pullup or pulldown value may appear higher when
measured externally on the pin.
3 All functional non-supply pins, except for PTA5 are internally clamped to V
SS and VDD.
4 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.
5 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. Examples are: if no system clock is
present, or if clock rate is very low (which would reduce overall power consumption).
6 Maximum is highest voltage that POR is guaranteed.
7 When V
DD is in between the minimun of this parameter and 4.5 V, the CPU, RAM, LVD and flash are full functional, but the
performance of other modules may be reduced.
8 Factory trimmed at V
DD = 5.0 V, Temp = 25 C
