Notes:
1. Not 100 % tested.
2. In the pre-programming step of the Embedded Erase algorithm, all bytes are programmed to 00h before erasure.
3. Typical program and erase time assume the following conditions :25℃,3.0 V VDD, 100,000 cycles .Additionally,
programming typicals assume checkerboard pattern.
4. Under worst case conditions of 90℃, VDD =2.7V, 100,000 cycles.
5. The typical chip programming time is considerably less than the maximun chip programming time listed,since most
bytes program faster than maximun program times listed.
6. System-level overhead is the time required to execute the two- or four-bus-cycle sequence for the program command.
7. The device has a minimum erase and program cycle endurance of 100,000 cycles.
