Note 1: Data in “Typ” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only
and are not tested.
2: This is the limit to which V
DD can be lowered without losing RAM data.
3: Device will operate normally until Brown-out reset occurs even though V
DD may be below VDDMIN.
