NOTES:

1. VDD = 5.0 Vdc ±10%, VSS = 0 Vdc, TA = 0 °C to +70 °C, unless otherwise noted

2. All values shown reﬂect average measurements.

3. Typical values at midpoint of voltage range, 25

°C only

4. Wait IDD and IDD2 : Only timer system active.

5. Run (operating) IDD, IDD2, Wait IDD, and IDD2: Measured using external square wave clock source (fOSC = 10.24 MHz); all inputs 0.2 V

from rail; no dc loads; less than 50 pF on all outputs; CL = 20 pF on OSC2

6. Wait, stop IDD: All ports conﬁgured as inputs, VIL = 0.2 V, VIH = VDD –0.2 V

7. Stop IDD and IDD2 are measured with OSC1 = VSS.

8. Wait IDD and IDD2 are affected linearly by the OSC2 capacitance.

9. Run, wait, and stop IDD2 are measured directly off the VDD2 power supply.
