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
1#, CE2#, 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 A when VIN = GND due to
internal pull-up resistors.
CMOS Test Conditions: VIL = VSS ± 0.2V, VIH = VCC ± 0.2V

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