Notes:
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.

Battery backup time is a
calculated value and is not
guaranteed. This should not be
used to schedule battery
recharging. (Temp 25C)
Notes:
1. Battery Life refers to functional lifetime of battery.
2. Battery backup time is density and temperature dependent.
