1 Typical program and erase times are calculated at 25 oC operating temperature using nominal supply values.

Initial

Max. 2

2 Initial factory condition:

≤ 100 program/erase cycles, 25 oC, using a typical supply voltage measured at a minimum system

frequency of 80 MHz.

Max. 3

3 The maximum erase time occurs after the specified number of program/erase cycles. This maximum value is characterized

but not guaranteed.
