22.6 DC Electrical Characteristics
1. VDD = 5.0 Vdc ± 10%, 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 (fosc = 8.2 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 capacitance linearly affects Run
IDD. Measured with all modules enabled.
4. Wait IDD measured using external square wave clock source (fosc = 8.2 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 capacitance linearly affects Wait IDD. Mea-
sured with PLL, LCD, LVI, and TBM enabled.
5. Stop IDD measured with OSC1 = VSS.
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.
