* 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: 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 CLKIN 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, V
DD 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 23-5).
