Self-programming ROM for store data

Hi to all,
I need to realize a standalone sensor with DA14580. ARM Cortex M0 read external sensor and transmit measurement to remote device by Ble.
In my particular application the MCU power off entire circuit after some seconds.
However before power-off, MCU need to save some bytes of data to memory.
Instead of using an external EEProm, it would be possible to write data to internal ROM? If yes, what is the maximum number of read-write cycles that the memory is able to make before breaking down?

Hi Giuseppe, ROM is not

Hi Giuseppe, ROM is not accessible to the user : its writen during manufacture of the chip. You will need to use either DA14583 with external FLASH or use some a small external EEPROM or FLASH with DA14580.
