Power supply voltage VDDD, VDDA -0.5 to 4.6V Note: Stresses beyond those listed
under “Absolute Maximum
Ratings” may cause permanent
damage to the device. These are
stress ratings only and functional
operation of the device at these or
any other conditions beyond those
indicated in the operational
sections of this specification is not
implied. Exposure to absolute
