These parameters are characterized but not tested.
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.
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.
