Voltage On Any Pin
(except VDD and VPP) ......... .......................................................................................... -0.5V to VDD +0.5V(2)
VDD and VDDQ Supply Voltage................................................................................................. -0.2V to +3.9V(2)
VPP Supply Voltage..................................................................................................... .... -0.2V to +12.6V(2,3,4)

*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 VSS. Minimum DC voltage is -0.5V on input/output pins and -0.2V on VDD and VPP
pins. During transitions, this level may undershoot to -2.0V for periods <20 nS. Maximum DC voltage on input/output pins and
VDD is VDD +0.5V, which, during transitions, may overshoot to VDD +2.0V for periods <20 nS.
3. Maximum DC voltage on VPP may overshoot to +13.0V for periods <20 nS.
4. VPP erase/program voltage is normally 2.7V to 3.6V. Applying 11.7V to 12.3V to VPP 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. VPP may be connected to 11.7V to
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 VPP = 11.7V to 12.3V during an 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 VPP =11.7V to 12.3V is not allowed and can cause
damage to the device.
