In my application, based on this default value of the EEPROM, its gonna
perform some 'X' task. If in future this default value i.e. 0xFF would
change then my application won't perform 'X' task. That is why I want to
be 100% sure whether it has to be 0xFF or not.
Just a doubt, If it comes in erased state why datasheet does not mention
about it ??

Non-volatile memory like EEPROM always comes in the 'erased' state IOW
0xFF.
So, this is normal in your EEPROM.
AFAIK the only exception is large NAND flash, which can/will have bad
sector
markers.

Subject: [msp430] Default value in EEPROM 24XX series
We are using 24XX series EEPROM of microchip make. I have read the data
from
the EEPROM (without writing data to EEPROM), it always give as 0xFF.
Atleast
i have checked in 5 EEPROM.
In the datasheet, it is not mentioned what should be the default value?
Could anyone let me know what should be the default value in EEPROM.
