Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and test conditions, see the Electrical Characteristics tables.
Note 2:
Data sheet minimum and maximum limits are guaranteed by design, test, or statistical analysis.
Note 3:
Supply current is measured with inputs connected to V
CC
and outputs driven low but not connected to a load.
Note 4:
T
C
= instruction cycle time (min. 0.7 μs).
Note 5:
In Halt mode, the internal clock is switched off. Supply current in Halt mode is measured with inputs connected to V
CC
and outputs driven low but not
connected to a load.
Note 6:
Guaranteed by design, not tested.
