Absolute Maximum Ratings2
Notes:
Operating Temperature TA (ambient)
1. During transitions, inputs may undershoot to -2.0V or overshoot to VCC +2.0V for
periods less than 20ns.
Commercial
Industrial
0°C to +60 °C
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: CE1#, 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.
CCS 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.
I
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
