Electrical Specifications
11.1
Absolute Maximum Ratings
NOTES:
1. All specified voltages are with respect to V
SS
. Minimum DC voltage is –0.5 V on input/output signals and
–0.2 V on V
CC
and V
PP
supplies. During transitions, this level may undershoot to –2.0 V for periods <20 ns
which, during transitions, may overshoot to V
CC
+2.0 V for periods <20 ns.
2. Maximum DC voltage on V
PP
may overshoot to +14.0 V for periods <20 ns.
3. V
PP
program voltage is normally V
PP1
. V
PP
can be V
PP2
for 1000 cycles on the main blocks and 2500 cycles
on the parameter blocks during program/erase.
4. Output shorted for no more than one second. No more than one output shorted at a time.
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.
