RECOMMENDED DC OPERATING CONDITIONS
(VCC = 3.3V -5%/+10% UNLESS OTHERWISE NOTED)
ABSOLUTE MAXIMUM RATINGS
*Stress 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 greater than those
indicated in operational sections of this specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect reliability.

NOTES:
1. ICC (operating) is specified with no output current. ICC (operating) increases with faster cycle times and greater output loading.
2. “Device idle” means device is deselected (CE
VIH) Clock is running at max frequency and Addresses are switching each cycle.
3. Typical values are measured at 3.3V, 25C. ICC (operating) is specified at specified frequency.
