NOTICE: This datasheet contains preliminary information on
new products in production. Do not finalize a design with
this information. Revised information will be published when
the product is available. Verify with your local Intel Sales
office that you have the latest data sheet before finalizing a
design.
* 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 effect device
reliability.
NOTES:
1.
Minimum DC voltage is
–0.5V on input/output pins.
During transitions, this level may undershoot to –2.0V
for periods < 20 ns. Maximum DC voltage on
input/output pins is V
+ 0.5V which, during
transitions, may overshoot to V
CC
+ 2.0V for periods <
20 ns.
2.
Maximum DC voltage on V
PP
may overshoot to +14.0V
for periods < 20 ns.
3.
Output shorted for no more than one second. No more
than one output shorted at a time.
4.
V
Program voltage is normally 2.7V–3.6V.
Connection to supply of 11.4V–12.6V can only be done
for 1000 cycles on the main blocks and 2500 cycles on
the parameter blocks during program/erase. V
PP
may
be connected to 12V for a total of 80 hours maximum.
See Section 3.4 for details.

–12.6V during a program/erase can only be done for a maximum of 1000 cycles on the main blocks
and 2500 cycles on the parameter blocks. V

may be connected to 12V for a total of 80 hours maximum. See Section 3.4
for details.
