ABSOLUTE MAXIMUM RATINGS
(1)
over operating free-air temperature range (unless otherwise noted)
VDD
Core supply voltage range
–0.3 V to 4 V
VIO
I/O supply voltage range
–0.3 V to 4 V
VI
Digital input voltage
–0.3 V to 4 V
TA

(1)
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 under recommended operating
conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
TA = 25°C, VDD = 3.3 V, and VIO = 3.3 V (unless otherwise noted)
