Conditions
Note
1:
Trip point is ±1.5% from typical value.
2:
Trip point is ±2.5% from typical value.
3:
RST output is forced low. There is a current through the internal pull-up resistor.
4:
This includes the current through the internal pull-up resistor and the reset power-up timer.
5:
This specification allows this device to be used in PIC® microcontroller applications that require In-Circuit Serial
Programming™ (ICSP™) (see device-specific programming specifications for voltage requirements). This specification
DOES NOT allow a continuous high voltage to be present on the open-drain output pin (VOUT). The total time that the
VOUT pin can be above the maximum device operational voltage (5.5V) is 100s. Current into the VOUT pin should be
limited to 2 mA and it is recommended that the device operational temperature be maintained between 0°C to 70°C
(+25°C preferred). For additional information, please refer to Figure 2-33.
6:
This parameter is established by characterization and not 100% tested.
