0.05 — — V/ms Ensures that the Power-on Reset
signal is released properly.
* 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: This is the limit to which VDD can be lowered in Sleep mode without losing RAM data.
2: PLL required for 32 MHz operation.
3: See Figure 30-3: POR and POR Rearm with Slow Rising VDD.
