Conditions

These parameters are characterized but not tested.

Note 1:

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.

All speciﬁed values are based on characterization data for that particular oscillator type under standard operating

conditions with the device executing code. Exceeding these speciﬁed limits may result in an unstable oscillator operation

and/or higher than expected current consumption.

When an external clock input is used, the “max” cycle time limit is “DC” (no clock) for all devices.

Instruction cycle period (TCY) equals four times the input oscillator time base period.
