* These parameters are characterized but not tested.

† 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: 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.

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