Notes
10. The erase/write cycle limit per block (Flash
ENPB
) is only guaranteed if the device operates within one voltage range. Voltage ranges are 3.0 V to 3.6 V and 4.75 V to
5.25 V.
11. For the full temperature range, the user must employ a temperature sensor user module (FlashTemp) or other temperature sensor, and feed the result to the temperature
argument before writing. Refer to the Flash APIs Application Note AN2015 for more information.
12. The maximum total number of allowed erase/write cycles is the minimum Flash
ENPB
value multiplied by the number of flash blocks in the device.
