Note: In any case or time period (greater than 1 ns), the supply voltage should comply with 3.3V > 1.8V
Recommended Operating Conditions (Sheet 2 of 2)
a. Sustained operation of the device at conditions exceeding these values, even if they are within the absolute maximum rating
b. The value listed in this table is for external voltage regulation. If the internal voltage regulator is used, the minimum value is
c. The value listed in this table is for external voltage regulation. If the internal voltage regulator is used, the maximum value is
d. The value listed in this table is for external voltage regulation. If the internal voltage regulator is used, the minimum value is
e. The value listed in this table is for external voltage regulation. If the internal voltage regulator is used, the maximum value is
Voltage Ramp and Sequencing Recommendations
> 1.2V. This is important to avoid stress in the ESD protection circuits. After 3.3V reaches 10% of
its final value, all voltage rails (1.8V and 1.2V) have 150 ms to reach their final operating values.
