An output current above |

IOXnom| may be drawn from up to three pins at the same time.

For any group of 16 neighboring port output pins the total output current in each direction (

ΣI

OL and Σ-IOH)

must remain below 50 mA.

During Flash programming or erase operations the supply current is increased by max. 5 mA.

The supply current is a function of the operating frequency. This dependency is illustrated in Figure 11.

These parameters are tested at

VDDImax and maximum CPU clock frequency with all outputs disconnected and

all inputs at

VIL or VIH.

Pad supply current

IDDP

–5

The pad supply voltage pins (

VDDP) 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

VDDP supply.

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).
