ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. Typical program and erase times assume the following conditions: 25
2. Under worst case conditions of 90°C, V
3. The typical chip programming time is considerably less than the maximum chip programming time listed.
4. In the pre-programming step of the Embedded Erase algorithm, all words are programmed to 00h before erasure.
5. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See
6. The device has a minimum erase and program cycle endurance of 1 million cycles.
