* 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.
Note 1: All specified values are based on characterization data for that particular oscillator type under standard oper-
ating 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 (T
CY) equals four times the input oscillator time base period.
