* These parameters are characterized but not tested.
† Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. These parameters are for design guidance only and are not
tested.
Note 1: This is the limit to which VDD can be lowered in Sleep mode without losing RAM data.
2: PLL required for 32 MHz operation.
