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
measured with PLL and LVI enabled.
;
5. Stop IDD measured with PLL and LVI disengaged, OCS1 grounded, no port pins sourcing current. It is measured through
combination of VDD, VDDAD, and VDDA
.
6. The low-voltage inhibit reset is software selectable. Refer to Section 9. Low-Voltage Inhibit (LVI).
7. Maximum is highest voltage that POR is guaranteed.
8. If minimum VDD is not reached before the internal POR is released, RST must be driven low externally until minimum VDD
is reached.
9. Maximum is highest voltage that POR is possible.
