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,

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!

STM8 has no signature id.

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.

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!

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

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.

Hi governatori,

I am using STVD.

Herzlich,

Hi MCU Lüfter,

   thanks for feedback!

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

   Thanks!

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.
