These parameters are characterized but not tested.

Data in “Typ” column is at 5.0V, 25

°C unless otherwise stated. These parameters are for design guidance only

and are not tested.

Note 1: Instruction cycle period (Tcy) equals four times the input oscillator time-based period. 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. All devices are tested to operate at “Min.”

values with an external clock applied to the OSC1 pin. When an external clock input is used, the “Max”

cycle time limit is “DC” (no clock) for all devices.
