Electrical characteristics

Freescale Semiconductor

NOTES:

1 Typical program and erase times represent the median performance and assume nominal supply values and operation at

25C. These values are characterized, but not tested.

2 For memory sizes greater than 1MB, and for blocks with less than or equal to 100 program/erase cycles, the user can apply

a 90% typical + 10% Init Max (25C or All Temps depending on temperature) for each unit (page or block) to calculate the total

program or erase time.

3 Initial Max 25C program and erase times provide guidance for time-out limits used in the factory and apply for less than or

equal to 100 program or erase cycles, 20C < Tj < 30C junction temperature, and nominal (+/- 2%) supply voltages. These

values are verified at production test.

4 Initial Max All Temps program and erase times provide guidance for time-out limits used in the factory and apply for less than

or equal to 100 program or erase cycles, -40C < Tj < 150C junction temperature, and nominal (+/- 2%) supply voltages. These

values are verified at production test.

5 Lifetime Max program and erase times apply across the voltage, temperature and cycling range of product life. This maximum

value is characterized but not tested.

6 Program times are actual hardware programming times and do not include software overhead.

7 Program times are actual hardware programming times and do not include software overhead.

8 Program times are actual hardware programming times and do not include software overhead.
