Maximum Ratings and Operating Conditions

5.1

Absolute Maximum Ratings

Warning:

Stressing the device beyond the “Absolute Maximum Ratings” may cause permanent

damage. These ratings are stress ratings only. Operation beyond the “Operating

Conditions” is not recommended, and extended exposure beyond the “Operating

Conditions” may affect device reliability.

5.2

Operating Conditions

NOTICE: Specifications are subject to change without notice. Verify with your local Numonyx Sales office that you have the

latest datasheet before finalizing a design.

Voltage On Any Pin (except VCC and VPP) with Respect to GND

–0.5 V to +3.7 V

VPP Voltage (for Block Erase and Program) with Respect to GND

–0.5 V to +13.5 V

VCC and VCCQ Supply Voltage with Respect to GND

–0.2 V to +3.6 V

Output Short Circuit Current

100 mA

Notes:

Minimum DC voltage is –0.5 V on input/output pins. During transitions, this level may undershoot to –2.0 V

for periods <20 ns. Maximum DC voltage on input/output pins is VCC +0.5 V which, during transitions, may

overshoot to VCC +2.0 V for periods <20 ns.

Maximum DC voltage on VPP may overshoot to +14.0 V for periods <20 ns.

VPP Program voltage is normally 1.65 V–3.6 V. Connection to a 11.4 V–12.6 V supply can be done for a

maximum of 1000 cycles on the main blocks and 2500 cycles on the parameter blocks during program/

erase. VPP may be connected to 12 V for a total of 80 hours maximum.

Output shorted for no more than one second. No more than one output shorted at a time.
