Note 1: Trip point is ±1.5% from typical value.
2: Trip point is ±2.5% from typical value.
3: Hyster ysis is minimum = 1%, maximum = 6% at +25°C.
4: This specification allows this device to be used in PIC
®
microcontroller applications that require the In-Circuit Serial Programming™ (ICSP™) feature (see device-specific programming specifications for voltage
requirements). The total time that the RST
(5.5V) is 100s. Current into the RST
pin can be above the maximum device operational voltage
pin should be limited to 2 mA. It is recommended that the device operational temperature be maintained between 0°C to +70°C (+25°C preferred). For additional information,
refer to Figure 2-35.
