45 / 82 page ![]() &3, Data Sheet 43 1999-07 Figure 9 Idle and Power Down Supply Current as a Function of Oscillator Frequency 7) The supply current is a function of the operating frequency. This dependency is illustrated in the figure below. These parameters are tested at 9 DDmax and maximum CPU clock with all outputs disconnected and all inputs at 9 IL or 9IH. The oscillator also contributes to the total supply current. The given values refer to the worst case, ie. I PDRmax. For lower oscillator frequencies the respective supply current can be reduced accordingly. 8) This parameter is determined mainly by the current consumed by the oscillator. This current, however, is influenced by the external oscillator circuitry (crystal, capacitors). The values given refer to a typical circuitry and may change in case of a not optimized external oscillator circuitry. 9) This parameter is tested including leakage currents. All inputs (including pins configured as inputs) at 0 V to 0.1 V or at 9 DD – 0.1 V to 9DD, 9REF = 0 V, all outputs (including pins configured as outputs) disconnected.
