* 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.
Note 1: 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.
2: See Figure 31-60 and Figure 31-61: LFINTOSC Frequency Characteristics over VDD and Temperature.
