    Are you talking about a pack you are producing, or a pack that someone else produced?

    By default there is no serial number.  By this I mean each IC does not have it's own serial number.  However, there are some dataflash locations that can be used to store a serial number or other information like lot code, manufacture date, etc. This will have to be programmed in your production line, or you can leave it blank.

    Hi Micou,

    These were programmed in the dataflash, so there is no RAM register to read them directly.

    You need to use the BlockData transfer commands to read out those dataflash parameters you mentioned.
