Power supply must maintain regulation within operating V
DD
range during instantaneous and operating maximum
current conditions. If positive injection current (VIn > VDD) 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 clock rate is very low (which would reduce overall power
consumption).
6
All functional non-supply pins are internally clamped to VSS and V
DD
.
7
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.
8
The RESET pin does not have a clamp diode to V
DD
. Do not drive this pin above V
DD
.
