Typical values are measured at 25°C. Characterized, not tested
2
When a pin interrupt is configured to detect rising edges, pulldown resistors are used in place of pullup resistors.
3
The specified resistor value is the actual value internal to the device. The pullup value may measure higher when measured
externally on the pin.
4
Power supply must maintain regulation within operating V
DD
range during instantaneous and operating maximum current
conditions. If 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 external V
DD
load shunts current greater than maximum injection
current. This is the greatest risk when the MCU is not consuming power. For example, if no system clock is present, or if clock
rate is very low (which would reduce overall power consumption).
5
All functional non-supply pins except RESET are internally clamped to V
SS
and V
DD
.
6
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.
7
The RESET pin does not have a clamp diode to V
DD
. Do not drive this pin above V
DD
.
8
Maximum is highest voltage that POR is guaranteed.
