*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.

1.2 Operating Conditions
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.
