    Hi Michael,

    I'm working on it.  I'm having to reach out to several different people to find this information and it may take time.

    Hi Michael,

    Ok, here is what I found.

    I'm being told we do not have a formal document discussing the volatility of the memory elements in the design.

    However,

    I can provide general information that covers this.

    The memory is organized as Main Flash: (16 x 512 byte) 8KB

    Information Flash: (4 x 64bit) 256 byte

    RAM: 256 byte.

    Peripheral RAM: 512 byte.

    From the above list, the items labeled Flash are non-volatile, and will retain their contents through a power cycle.

    Customer code/data can live in the Main Flash, and also in parts of the information flash.

    To clear any contents from the FLASH, it is required to erase the FLASH. 

    Parts of the information flash, will contain device specific data used for calibration and features.  If this is erased, then the calibration data is no longer usable. 

    Additionally, there are registers within the design implemented with flip flops or registers.   These registers will be cleared with a power cycle.

    The RAM block and peripheral memory will be cleared with a power cycle.

    The only memory that will be retained from a power cycle are the elements labeled Flash.

    Hopefully this provides enough information.
