Operating Temperature
During Read, Erase and Program ...-40°C to +85°C ⁽¹⁾
Storage Temperature
During under Bias............................... -40°C to +85°C
During non Bias................................ -65°C to +125°C
Voltage On Any Pin
(except V_CC and V_PP).............. -0.5V to V_CC+0.5V ⁽²⁾
V_CC and V_CCQ Supply Voltage .......... -0.2V to +3.9V ⁽²⁾

*WARNING: Stressing the device beyond the "Absolute
Maximum Ratings" may cause permanent
damage. These are stress ratings only. Operation
beyond the "Operating Conditions" is not
recommended and extended exposure beyond
the "Operating Conditions" may affect device
reliability.
NOTES:
1. Operating temperature is for extended temperature
product defined by this specification.
2. All specified voltages are with respect to GND.
Minimum DC voltage is -0.5V on input/output pins
and -0.2V on V_CC and V_PP pins. During transitions,
this level may undershoot to -2.0V for periods <20ns.
Maximum DC voltage on input/output pins is
V_CC+0.5V which, during transitions, may overshoot to
V_CC+2.0V for periods <20ns.
3. Maximum DC voltage on V_PP may overshoot to
+13.0V for periods <20ns.
4. V_PP erase/program voltage is normally 2.7V-3.6V.
Applying 11.7V-12.3V to V_PP during erase/program
can be done for a maximum of 1,000 cycles on the
main blocks and 1,000 cycles on the parameter blocks.
V_PP may be connected to 11.7V-12.3V for a total of 80
hours maximum.
5. Output shorted for no more than one second. No more
than one output shorted at a time.

NOTES:
1. See DC Characteristics tables for voltage range-specific specification.
2. Applying V_PP=11.7V-12.3V during a erase or program can be done for a maximum of 1,000 cycles on the main blocks
and 1,000 cycles on the parameter blocks. A permanent connection to V_PP=11.7V-12.3V is not allowed and can cause
damage to the device.
