Hello,

I need for my project to save only 32bit in non-volatile storage.
What is the easiest/cheapest way to do that in Arduino DUE?

ArduinoDUE is Atmel SAM3X8E so according to the attached table (from Atmel DS)

In the chip I have 4KB of NFC SRAM. NFC = Nand Flash Controller, so I have 4KB of internal flash in the internal SRAM?

Thanks,

If you need to store a 32-bit variable before a reset (without a power down), you have 4 32-bit General Purpose Back-up Registers(GPBR).

If you need to store a 32-bit variable before a power down, the DueFlashStorage library can be useful.
