DC Electrical Characteristics
(VDD = 5.0Vdc ± 10%, VSS = 0 Vdc, TA = 0 to 70οC)
Typical values at mid point of voltage range, 25οC only.
Wait IDD: Only timer system active. If Serial Interface active add 10% to current drain.
Run IDD, Wait IDD: Measured using external square clock source (Fosc = 8 MHz), all inputs 0.2V from rail, no DC loads,
maximum load on outputs 50pF (OSC2 load 20pF).
Wait, Stop IDD: All ports congured as inputs, Vil = 0.2V and
Vih = VDD - 0.2V.
Stop IDD measured with OSC1 = VSS. Wait IDD is affected linearly by the OSC2 capacitance.
