ABSOLUTE MAXIMUM RATINGS(1)
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. VDDQ and VDD internally operate independently. No power sequencing requirements
need to be met.
3. Not to exceed 3.6V.

RECOMMENDED OPERATING RANGE
NOTE:
1. All power supplies should operate in tandem. If VDD or VDDQ is at maximum, then VDDQ or VDD (respectively) should be at maximum, and vice-versa.
