This is a stress rating only and functional operation of the device at those or any other conditions above those indicated in the operational listings of this specification is not implied. Expo- sure to maximum rating conditions for extended periods may affect device reliability. DC CHARACTERISTICS Electrical Specifications: Unless otherwise indicated, all limits are specified for VDD = 1V to 5.5V, RPU = 100 k (only MCP1320, MCP1321 and MCP1322), TA = -40°C to +125°C. Parameters Sym Min Typ Max Units Conditions Operating Voltage Range VDD 1.0 — 5.5 V Specified VDD Value to VOUT Low VDD 1.0 — — V I RST = 10 µA, V RST < 0.3V Operating Current: IDD — 5 10 µA Watchdog Timer Active — 1 2 µA Watchdog Timer Inactive —1 2 µA VDD < VTRIP — 5 10 µA Reset Delay Timer Active Note 1: Trip point is ±1.5% from typical value. 2: Trip point is ±2.5% from typical value. 3: Hysteresis 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 pin can be above the maximum device operational voltage (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 information, 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.
