DS90UB960-Q1: something like unique chip number or DIE ID?

Hello Konstantin,

Yes it does. You can access the Unique ID through indirect registers 0xB0-0xB2. Set the indirect page (IA_SEL) to 1001 to access the unique ID in register 0xB0, then you can use registers 0xB1-0xB2 to access the ID. The ID is in indirect registers 0x00-0x0F

Best Regards,

Casey
