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: Supply current is measured with inputs connected to V

Note 3: T

Note 4: In standby mode, the internal clock is switched off. Supply current in standby mode is measured with inputs connected to V

not connected to a load.

Note 5: Applied to all digital pins (including RESET) except for SLOWCLK when configured for an external clock..

Note 6: Guaranteed by design, not tested.

Note 7: The sum of all I/O sink/source current must not e4xceed the maximum total current into V

ratings.
