Electrical characteristics

2. Actual hardware programming times; this does not include software overhead.

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

pending device characterization.

4. Typical End of Life program and erase times represent the median performance and assume nominal supply values.

Typical End of Life program and erase values may be used for throughput calculations. These values are characteristic, but

not tested.

5. Lifetime maximum program & erase times apply across the voltages and temperatures and occur after the specified

number of program/erase cycles. These maximum values are characterized but not tested or guaranteed.

6. Initial factory condition: < 100 program/erase cycles, 20 °C < TJ < 30 °C junction temperature, and nominal (± 2%) supply

voltages. These values are verified at production testing.

7. Initial maximum “All temp” 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, –40 °C < TJ < 150 °C junction temperature, and nominal (± 2%) supply

voltages. These values are verified at production testing.

8. Rate computed based on 256K sectors.

9. Only code sectors, not including EEPROM.

10. Time between erase suspend resume and next erase suspend.

11. Timings guaranteed by design.

12. AIC is done using system clock, thus all timing is dependant on system frequency and number of wait states. Timing in the

table is calculated at 160 MHz.
