2.2 Parameter 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:
NOTE
The classification is shown in the column labeled “C” in the parameter tables where
appropriate.
2.3 Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the
limits specified in Table 3 may affect device reliability or cause permanent damage to the device. For functional operating
conditions, refer to the remaining tables in this section.
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 V
SS
or V
DD
) or the programmable pull-up resistor associated with the pin is enabled.
Table 2. Parameter Classifications
P Those parameters that are guaranteed during production testing on each individual device.
C
Those parameters that are achieved by the design characterization by measuring a statistically relevant
sample size across process variations.
T
Those parameters that 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 that are derived mainly from simulations.

1
Input must be current limited to the value specified. To determine the value of the required
current-limiting resistor, calculate resistance values for positive (V
DD
) and negative (V
SS
) clamp
voltages, then use the larger of the two resistance values.
2
All functional non-supply pins, except for PTF1/RESET are internally clamped to V
SS
and V
DD
.
3
Power supply must maintain regulation within operating V
DD
range during instantaneous and
operating maximum current conditions. If positive injection current (V
In
> V
DD
) is greater than
I
DD
, the injection current may flow out of V
DD
and could result in external power supply going
out of regulation. Ensure external V
DD
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 the clock rate is very low (which would reduce overall power
consumption).
