* These parameters are characterized but not tested.

Note 1: Data in the Typical (“Typ”) column is at 5V, 25°C unless otherwise stated. These parameters are for design guidance only

and are not tested.

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

tions 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.

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