XMC: Serial Number or UID?
Hello at all,
does anyone know if the XMC microcontroller has a serial number or UID, which is unique assigned to this chip and which I can read? This number should exist only once in the world.
And how do I read these out? Or at which address range can I find this number?
Regards Patrick

Hi,
The unique chipid is 16bytes long.
In XMC1 family the unique chip id is located at 0x10000FF0.
In XMC4 familiy there is the g_chipid which is initialized at startup with the contents of the unique chip id, see SystemInit() in system_XMC4x00.

If I remember correctly, there are forum posts here which state that the unique ID isn't unique among several chips of the same batch.

Hi,
The chip id coded in the 16bytes is unique.

Hi,
The 16bytes chip id is absolute unique for every XMC4000/XMC1000.

Hello Jesus,
thank you for the clarification! In th case partial information in the referenced thread is wrong, which resulted in uncertainty among forum users - including myself.
Do you recommend linking it to this thread?
