Power Dissipation
When designing portable systems, designers must consider battery power consumption not only
during device operation, but also for data retention during system idle time. Flash memory’s
nonvolatility increases usable battery life because data is retained when system power is removed.

Electrical Specifications
6.1
Absolute Maximum Ratings
NOTES:
1. All specified voltages are with respect to GND. Minimum DC voltage is –0.5 V on input/output pins and –0.2 V
on VCC and VPEN pins. Duringtransitions, this level may undershoot to –2.0 V for periods <20 ns. Maximum
DC voltage on input/output pins, VCC, and VPEN is VCC +0.5 V which, duringtransitions, may overshoot to
VCC +2.0 V for periods <20 ns.
2. Maximum DC voltage on RP# may overshoot to +14.0 V for periods <20 ns.
3. RP# voltage is normally at VIL or VIH. Connection to supply of VHH is allowed for a maximum cumulative
period of 80 hours.
4. Output shorted for no more than one second. No more than one output shorted at a time.
5. Extended temperature for 0.4 micron ETOXTM V process technology is from -20° C to +85° C.
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.
