NOTES:
1. Typical ratings are not guaranteed. The values listed are at room temperature, 5 V.
2. See other Figures for details. Active mode: I
CC(MAX)
= tbd; Idle mode: I
CC(MAX)
= tbd
3. Ports in quasi-bidirectional mode with weak pull-up (applies to all port pins with pull-ups). Does not apply to open drain pins.
4. Ports in PUSH-PULL mode. Does not apply to open drain pins.
5. In all output modes except high impedance mode.
6. Port pins source a transition current when used in quasi-bidirectional mode and externally driven from 1 to 0. This current is highest when
V
IN
is approximately 2 V.
7. Measured with port in high impedance mode.
8. Measured with port in quasi-bidirectional mode.
9. Under steady state (non-transient) conditions, I
OL
must be externally limited as follows:
Maximum I
per port pin:
20 mA
Maximum total I
OL
for all outputs:
80 mA
Maximum total I
for all outputs:
5 mA
If I
exceeds the test condition, V
OL
may exceed the related specification. Pins are not guaranteed to sink current greater than the listed
test conditions.
10.Pin capacitance is characterized but not tested.
11. The I
, I
, and I
specifications are measured using an external clock with the following functions disabled: comparators, brownout
detect, and watchdog timer. For V
= 3 V, LPEP = 1. Refer to the appropriate figures on the following pages for additional current drawn by
each of these functions and detailed graphs for other frequency and voltage combinations.
12.Devices initially operating at V
= 2.7 V or above, and at f
= 10 MHz or less, are guaranteed to continue to execute instructions
correctly at the brownout trip point. Initial power-on operation below V
DD
= 2.7 V is not guaranteed.
13.Devices initially operating at V
DD
= 4.0 V or above and at f
OSC
= 20 MHz or less are guaranteed to continue to execute instructions correctly
at the brownout trip point. Initial power-on operation below V
DD
= 4.0 V and f
OSC
> 10 MHz is not guaranteed.
