Hi Geison Mancuzo,

    Yes, MK22FN1M0VLH12 don't have EERROM, so if you want to store the data, you can store it in the flash sector, eg, you use the last flash sector as your user area.

    One sector = 2KB size.

    But take care, flash is not EEPROM, when you want to modify it, you should erase the sector and program it again.

    About the flash operation sample code, you can refer to the FRDM-K22 ksdk sample code:

Wish it helps you!

If you still have question, please contact me!

Have a great day,
