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)
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. Parameter is guaranteed but not tested at cold temperature.
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
OH
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
DD
, I
ID
, and I
PD
specifications are measured using an external clock with the following functions disabled: comparators, brownout
detect, and watchdog timer.
12.Devices initially operating at V
DD
= 4.5V or above and at f
OSC
= 10 MHz or less are guaranteed to continue to execute instructions correctly
at the brownout trip point. Initial power-on operation below V
DD
= 4.5 V is not guaranteed.
