DC electrical characteristics
(1) Typical values are at midpoint of voltage range and at 25
°C only.
(2) All IDD measurements taken with suitable decoupling capacitors across the power supply to suppress the
transient switching currents inherent in CMOS designs. RUN and WAIT IDD: measured using an external
square-wave clock source (fOSC = 3.58 MHz); all inputs0.2V from rail; no DC loads; maximum load on outputs
50pF (20pF on OSC2). WAIT IDD: only the timer system and DMG active; current varies linearly with the OSC2
capacitance. STOP and WAIT IDD: all ports congured as inputs, VIL = 0.2 V, VIH = VDD 0.2 V. STOP IDD:
measured with OSC1 = VSS.
