3Parameter classification
The electrical parameters shown in this supplement are guaranteed by various methods.
To give the customer a better understanding, the following classification is used and the
parameters are tagged accordingly in the tables where appropriate:
Table 1. Parameter classifications
P Those parameters are guaranteed during production testing on each individual device.
C Those parameters are achieved by the design characterization by measuring a statistically relevant sample size
across process variations.
T Those parameters are achieved by design characterization on a small sample size from typical devices under
typical conditions unless otherwise noted. All values shown in the typical column are within this category.
D Those parameters are derived mainly from simulations.
NOTE
The classification is shown in the column labeled “C” in the
parameter tables where appropriate.

4.4 Voltage and current operating ratings
Absolute maximum ratings are stress ratings only, and functional operation at the
maxima is not guaranteed. Stress beyond the limits specified in the following table may
affect device reliability or cause permanent damage to the device. For functional
operating conditions, refer to the remaining tables in this document.
This device contains circuitry protecting against damage due to high static voltage or
electrical fields; however, it is advised that normal precautions be taken to avoid
application of any voltages higher than maximum-rated voltages to this high-impedance
circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate
logic voltage level (for instance, either VSS or VDD) or the programmable pullup resistor
associated with the pin is enabled.

VDD Digital supply voltage –0.3 6.0 V
IDD Maximum current into VDD — 120 mA

3. The specified resistor value is the actual value internal to the device. The pullup value may appear higher when measured
externally on the pin.
4. All functional non-supply pins, except for PTA2 and PTA3, are internally clamped to VSS and VDD. PTA2 and PTA3 are true
open drain I/O pins that are internally clamped to VSS.
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 value.
6. Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum current
conditions. If the positive injection current (VIn > VDD) is higher 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 higher than
maximum injection current when the MCU is not consuming power, such as when no system clock is present, or clock rate
is very low (which would reduce overall power consumption).
