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.

5 Typical Bank programming time assumes that all cells are programmed in a single pulse. In reality some cells will

require more than one pulse, adding a small overhead to total bank programming time (see Initial Max column).
