Freescale Semiconductor
dc injection current
Input capacitance (all non-supply pins)
Typicals are measured at 25°C.
This parameter is characterized and not tested on each device.
Measurement condition for pull resistors: V
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.
All functional non-supply pins are internally clamped to 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.
This parameter is characterized and not tested on each device.
IRQ does not have a clamp diode to V
