FLASH PROGRAM AND ERASE TIMES AND ENDURANCE CYCLES
The Program and Erase times and the number of
Program/ Erase cycles per block are shown in Ta-
ble 14. In the Flash memory the maximum number
of Program/ Erase cycles depends on the voltage
supply used.
Table 14. Flash Program, Erase Times and Endurance Cycles
