Legend: TBD = To Be Determined.

These parameters are characterized but not tested.

** These parameters are design targets and are not tested. No characterization data available at this time.

† Data in the Typical (“Typ”) column is at 5.0V, 25°C unless otherwise stated. These parameters are for

design guidance only and are not tested.

Note 1:

Measurements are taken in RC mode where CLKOUT output is 4 x TOSC.

Please refer to Figure 11-2 for load conditions.
