Typical

Value1

1 Typical program and erase times assume nominal supply values and operation at 25 °C. All times are subject to change

pending device characterization.

Initial

Max2

2 Initial factory condition: < 100 program/erase cycles, 25 °C, typical supply voltage.

Max3

3 The maximum program & erase times occur after the specified number of program/erase cycles. These maximum values are

characterized but not guaranteed.
