1 Typical program and erase times assume nominal supply values and operation at 25 °C.

Initial

max2

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

Max3

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

values are characterized but not guaranteed.
