This parameter is characterized and not tested on each device.
Measurement condition for pull resistors: V
All functional non-supply pins are internally clamped to V
V
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.
Power supply must maintain regulation within operating V
conditions. If positive injection current (V
in external power supply going out of regulation. Ensure external V
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.
This parameter is characterized and not tested on each device.
