This parameter is characterized before qualification rather than 100% tested.
pF load ratings are based on DC loading and are provided as an indication of driver strength. High speed interfaces
require transmission line analysis to determine proper drive strength and termination.
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.
The power supply must maintain regulation within operating V
current conditions. If positive injection current (V
and could result in external power supply going out of regulation. Ensure that the external V
greater than maximum injection current. This is 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. Also, the system
clock is not present during the power-up sequence until the PLL has attained lock.
