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. Parameters Sym Min Typ Max Units 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.
