Notes:
(1) During transitions, inputs may undershoot to
-2.0V or overshoot to VCC +2.0V for periods less
than 20ns.
(2) 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 at these or
any other conditions greater than those indicated
in the operational sections of this specification is
not implied. Exposure to absolute maximum rating
conditions for extended periods may affect
reliability.

Notes:
1. All currents are for x16 mode and are RMS values unless otherwise specified.
2. Control Signals: CE
#, CE
#, OE#, WE#, REG#.
3. Typical: VCC = 5V, T = +25C.
4. ICCS includes battery recharge current. Value depends on battery discharge level. ICCS min is specified for fully
charged battery. ICCS typical value is specified for battery discharge to 2.7V. ICCS max is specified for a fully
discharged battery (0V). Battery will recharge to 1.5V in 20 sec.
5. Values are the same for byte and word wide modes for all card densities.
6. Exceptions: Leakage currents on CE1#, CE2#, OE#, REG# and WE# will be < 500 μA when VIN = GND due to
internal pull-up resistors.
