5. Characteristics and Specifications
Note:
5.1 Absolute Maximum Ratings
(GNDD = GNDIO = GNDA = 0 V; all voltages with respect to 0V)
Caution: Operation at or beyond these limits may result in permanent damage to the device. Normal operation is
5.2 Recommended Operating Conditions
(GNDD = GNDIO = GNDA = 0 V; all voltages with respect to 0V)
Note: It is recommended that the 3.3 V IO supply come up ahead of or simultaneously with the 1.8 V core supply.
