NOTES:
1. Typical ratings are not guaranteed. The values listed are at room temperature, 5 V.
2. See other Figures for details.
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
VIN 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, IOL must be externally limited as follows:
Maximum IOL per port pin:
20 mA
Maximum total IOL for all outputs:
80 mA
Maximum total IOH for all outputs:
5 mA
If IOL exceeds the test condition, VOL 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 IDD, IID, and IPD specifications are measured using an external clock with the following functions disabled: comparators, brownout
detect, and watchdog timer. For VDD = 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 VDD = 2.7V or above and at fOSC = 10 MHz or less are guaranteed to continue to execute instructions correctly
at the brownout trip point. Initial power-on operation below VDD = 2.7 V is not guaranteed.

VDD = 3.0 V to 6.0 V unless otherwise specified; Tamb = 0°C to +70°C or –40°C to +85°C, unless otherwise specified
