1) During Flash programming or erase operations the supply current is increased by max. 5 mA.
2) The supply current is a function of the operating frequency. This dependency is illustrated in Figure 11.
These parameters are tested at V_DDImax and maximum CPU clock frequency with all outputs disconnected and
all inputs at V_IL or V_IH.
3) The pad supply voltage pins (V_DDP) mainly provides the current consumed by the pin output drivers. A small
amount of current is consumed even though no outputs are driven, because the drivers’ input stages are
switched and also the Flash module draws some power from the V_DDP supply.
4) The total supply current in Sleep and Power down mode is the sum of the temperature dependent leakage
current and the frequency dependent current for RTC and main oscillator (if active).
5) This parameter is determined mainly by the transistor leakage currents. This current heavily depends on the
junction temperature (see Figure 13). The junction temperature T_J is the same as the ambient temperature T_A
if no current flows through the port output drivers. Otherwise, the resulting temperature difference must be
taken into account.
6) All inputs (including pins configured as inputs) at 0 V to 0.1 V or at V_DDP - 0.1 V to V_DDP, all outputs (including
pins configured as outputs) disconnected. This parameter is tested at 25 °C and is valid for T_J ≥ 25 °C.
7) This parameter is determined mainly by the current consumed by the oscillator switched to low gain mode (see
Figure 12). This current, however, is influenced by the external oscillator circuitry (crystal, capacitors). The
given values refer to a typical circuitry and may change in case of a not optimized external oscillator circuitry.
