ABSOLUTE MAXIMUM RATINGS
Storage Temperature
Ambient Temperature
Under Bias
Supply Voltage to AVSS or VSSB or VSSBS or DVSS
(AVDD, VDD, VDDB, VDDBS, DVDD)
Stresses above those listed under Absolute Maximum Rat-
ings may cause permanent device failure. Functionality at or
above these limits is not implied. Exposure to absolute maxi-
mum ratings for extended periods may affect device reliability.
