Typical values are measured at 25°C. Characterized, not tested
2
All I/O pins except for LCD pins in Open Drain mode.
3
Total leakage current is the sum value for all GPIO pins. This leakage current is not distributed evenly across all pins but
characterization data shows that individual pin leakage current maximums are less than 250 nA.
4
All functional non-supply pins, except for PTB2 are internally clamped to V
SS
and V
DD
.
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 V
DD
range during instantaneous and operating maximum current
conditions. If the 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 that 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 clock rate is very low (which would reduce overall power consumption).
7
POR will occur below the minimum voltage.
