Program and Erase Times and Endurance Cycles
Table 21 lists both program and erase times plus the number of program/erase cycles per block. Exact erase times can vary
depending on the memory array condition. The best case is when all the bits in the block are at ‘0’ (pre-programmed). The
worst case is when all the bits in the block are at ‘1’ (not preprogrammed). Usually, the system overhead is negligible with
respect to the erase time. The maximum number of program/erase cycles depends on the VPP voltage supply used.

Notes:
1.
TA = –25°C to 85 °C; VDD = 1.7V to 2V; VDDQ = 2.3V to 2.7V or 3.0V to 3.6V.
2.
Values are liable to change with the external system-level overhead (command sequence and Status Register polling execution).
3.
Excludes the time needed to execute the command sequence.
4.
This is an average value on the entire device.
