Notes

1) This specification is not valid for outputs which are switched to open drain mode. In this case the respective

output will float and the voltage results from the external circuitry.

2) The maximum current may be drawn while the respective signal line remains inactive.

3) The minimum current must be drawn in order to drive the respective signal line active.

4) This specification is only valid during Reset, or during Adapt-mode.

5) Not 100% tested, guaranteed by design characterization.

6) The supply current is a function of the operating frequency. This dependency is illustrated in the figure below.

These parameters are tested at

VDDmax and 20 MHz CPU clock with all outputs disconnected and all inputs at

VIL or VIH.

The oscillator also contributes to the total supply current. The given values refer to the worst case, i.e.

IPDRmax.

For lower oscillator frequencies the respective supply current can be reduced accordingly.

7) This parameter is tested including leakage currents. All inputs (including pins configured as inputs) at 0 V to

0.1 V or at

VDD – 0.1 V to VDD, VREF = 0 V, all outputs (including pins configured as outputs) disconnected.

8) Overload conditions under operating conditions occur if the voltage on the respective pin exceeds the specified

operating range (i.e.

VOV > VDD +0.5 V or VOV < VSS - 0.5 V). The absolute sum of input overload currents on

all port pins may not exceed 50 mA. The supply voltage (

VDD and VSS) must remain within the specified limits.

9) 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 for

IPDR refer to a typical

circuitry and may change in case of a not optimized external oscillator circuitry.

A typical value for

IPDR at room temperature and fCPU = 16 MHz is 300 µA.
