11.8.7 Erase and Programming Performance
Notes:
1.
Typical program and erase times assume the following conditions: 25°C, 1.8 V VCC, 10,000
cycles; checkerboard data pattern.
2. Under worst case conditions of 90°C, VCC = 1.70 V, 100,000 cycles.
3. Typical chip programming time is considerably less than the maximum chip programming
time listed, and is based on single word programming.
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 the Appendix for further information on command
definitions.
6. Contact the local sales office for minimum cycling endurance values in specific applications
and operating conditions.
7. Refer to Application Note “Erase Suspend/Resume Timing” for more details.
8. Word programming specification is based upon a single word programming operation not
utilizing the write buffer.
