* These parameters are characterized but not tested.
† Data in the Typical (“Typ”) column is based on characterization results at 25°C. This data is for design guid-
ance only and is 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.
