1)2)
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.
