    Hi graz,

    In the datasheet I have found only that a unique 96-bit ID is available.

    I don't know what you are looking for is really available.

    Ciao,

    I don't think user is allowed to know where these informations are stored (this seems not specified anywhere in the documentation). The only kind of information you can retrive is 96-bit unique ID starting from location 0x48CD as specified in the datasheet.

    STM8 has no signature id.

    Hi all!

       Thanks for replies, for first!

       Some questions left: in which manual did you find that unique 96-bit ID is at 48CD location?

       And more: I suppose that STM8 has a signature, and it's hidden; how can you say that it does not have one? Please, if you refer to some paper, attach the link, that information would be valuable!

       Have a nice day!

    Hi governatori,

    In the device datasheet you will find it.

    In the following link you can download the device datasheet

    http://www.st.com/mcu/familiesdocs-113.html

    In attachement you find an example for STM8S105 devices.

    Ciao,

    the info on address location is on STM8S207/208 datasheet.

    Hi All,

       I've noticed that info about UniqueID, was inserted in Revision 9 of Datasheet (I was working on rev 7, that's why it wasn't reported), so thanks for the advice.

       Apart from this, I wonder how debug tools can recognise the micro, I would expect there's something hardcoded in memory space...

       Thank you guys again!

    Hi governatori,

    You are right I have change the MCU selection and I have got ''detected MCU different from selected one''. I think as you have said there it is somewhere hidden.

    Regards,

    Hi MCU Lüfter,

       thanks for feedback!

       What toolchain are you using? ST ''default'' or a third part one?

       Thanks!
