NOTES:
1. VDD = 5.0 Vdc ± 10%, VSS = 0 Vdc, TA = –40 °C to +105 °C, unless otherwise noted.
2. Typical values reflect average measurements at midpoint of voltage range, 25 °C only.
3. Run (Operating) IDD measured using external square wave clock source (fOP = 8.4 MHz). All inputs 0.2 V from rail.
No dc loads. Less than 100 pF on all outputs. CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capaci-
tance linearly affects run IDD. Measured with all modules enabled.
4. Wait IDD measured using external square wave clock source (fOP = 8.4 MHz). All inputs 0.2 Vdc from rail. No dc
loads. Less than 100 pF on all outputs, CL = 20 pF on OSC2. All ports configured as inputs. OSC2 capacitance
linearly affects wait IDD. Measured with all modules enabled.
5. Stop IDD measured with OSC1 = VSS.
6. Maximum is highest voltage that POR is guaranteed.
7. Maximum is highest voltage that POR is possible.
8. If minimum VDD is not reached before the internal POR reset is released, RST must be driven low externally until
minimum VDD is reached.
9. See 13.9 COP Module During Break Interrupts.
