NOTES:

See DC Characteristics tables for voltage range-specific specifications.

Applying VPP = 11.4V–12.6V during program/erase can only be done for a maximum of 1000 cycles on the main blocks

and 2500 cycles on the parameter. VPP may be connected to 12V for a total of 80 hours maximum. See Section 3.4 for

details.

For operating temperatures of –25

°C– +85°C the device is projected to have a minimum block erase cycling of 10,000 to

30,000 cycles.

The voltage swing on the inputs, VIN is required to match VCCQ.

DC Characteristics: VCCQ = 1.8V–2.2V

These tables are valid for the following power supply combinations only:

VCC1 and VCCQ and (VPP1 or VPP3)

VCC2 and VCCQ and (VPP2 or VPP3)

Wherever the input voltage VIN is mentioned, it is required that VIN matches the chosen VCCQ.
