ERASE AND PROGRAMMING PERFORMANCE
Notes:
1. Typical program and erase times assume the following conditions: 25°C, 3.0 V V
2. Under worst case conditions of 90°C, V
3. Effective write buffer specification is based upon a 16-word write buffer operation.
4. The typical chip programming time is considerably less than the maximum chip programming time listed, since most words
5. In the pre-programming step of the Embedded Erase algorithm, all bits are programmed to 00h before erasure.
6. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command. See Table
7. The device has a minimum erase and program cycle endurance of 100,000 cycles.
