1. VDD = 4.5 to 5.5 Vdc, VSS = 0 Vdc, TA = TL to TH, 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 = 8MHz). All inputs 0.2V 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
run IDD. Measured with all modules enabled.
4. Wait IDD measured using external square wave clock source (fOP = 8MHz). All inputs 0.2V 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.
5. Stop IDD measured with OSC1 grounded; no port pins sourcing current. LVI is disabled.
6. Maximum is highest voltage that POR is guaranteed.
7. If minimum VDD is not reached before the internal POR reset is released, RST must be driven low externally until minimum VDD is reached.
8. RPU1 and RPU2 are measured at VDD = 5.0V.
