I need to use a flash sector block for my data storage.
I have read in data-sheet that whit "Copy RAM to Flash" IAP function is possible write only 256, 512, 1024 or 4096 byte.
Prompt if I must write only 10 bytes will always have to write at least 256.
This limit applies to all sectors?

Yes, you can only write in those sizes. If you want to write 10 bytes you must pad it out to 256.

You could always read the 256 bytes that you want to overwrite, change the 10 bytes you want to replace, and then write the 256 bytes back...
