Note 1:
These parameters are characterized but not tested.
Data in “Typ” column is at 3.0V, 25°C unless otherwise stated. These parameters are for design guidance only and are
not tested.
Instruction cycle period (TCY) equals four times the input oscillator time base 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 CLKIN pin. When an
external clock input is used, the “max” cycle time limit is “DC” (no clock) for all devices.

† 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: 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.
2: To ensure these oscillator frequency tolerances, VDD and VSS must be capacitively decoupled as close to
the device as possible. 0.1 F and 0.01 F values in parallel are recommended.
3: The frequency tolerance of the internal oscillator is ±2% from 0-60°C and ±3% from 60-85°C
(see Figure 23-6).
