DC CHARACTERISTICS (CONTINUED)
Electrical Specifications: Unless otherwise indicated, all limits are specified for VDD = 1V to 5.5V, RPU = 100 kΩ
(only MCP1320, MCP1321 and MCP1322), TA = -40°C to +125°C.

Conditions
Note 1:
Trip point is ±1.5% from typical value.
2:
Trip point is ±2.5% from typical value.
3:
Hysterysis is minimum = 1%, max = 6% at +25°C.
4:
This specification allows this device to be used in PICmicro® 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 pin can be above the maximum device operational volt-
age (5.5V) is 100s. Current into the RST 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 informa-
tion, refer to Figure 2-35.
5:
This parameter is established by characterization and is not 100% tested.
6:
Custom ordered voltage trip point; minimum order volume requirement. Information available upon request.
