Maximum Ratings and Operating Conditions

13.1

Absolute Maximum Ratings

Warning:

Stressing the device beyond the Absolute Maximum Ratings may cause permanent

damage. These are stress ratings only.

13.2

Operating Conditions

Note:

Operation beyond the Operating Conditions is not recommended and extended

exposure beyond the Operating Conditions may affect device reliability.

Voltage on any signal (except VCC, VPP and VCCQ)

–0.5 V to +4.1 V

VPP voltage

VCC voltage

–0.2 V to +4.1 V

VCCQ voltage

–0.2 V to +4.1 V

Output short circuit current

100 mA

Notes:

Voltages shown are specified with respect to VSS. Minimum DC voltage is –0.5 V on input/output signals and –0.2 V on

VCC, VCCQ, and VPP. During transitions, this level may undershoot to –2.0 V for periods less than 20 ns. Maximum DC

voltage on VCC is VCC + 0.5 V, which, during transitions, may overshoot to VCC + 2.0 V for periods less than 20 ns.

Maximum DC voltage on input/output signals and VCCQ is VCCQ + 0.5 V, which, during transitions, may overshoot to

VCCQ + 2.0 V for periods less than 20 ns.

Maximum DC voltage on VPP may overshoot to +11.5 V for periods less than 20 ns.

Program/erase voltage is typically 2.3 V – 3.6 V. 9.0 V can be applied for 80 hours maximum total, to any blocks for

1000 cycles maximum. 9.0 V program/erase voltage may reduce block cycling capability.

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