AM2432: Does is have any product unique serial number each MCU?

Hello Seungho,

The memory space you mentioned is Reserved from a customer standpoint (hence lack of documentation). These are the DIE ID registers and are used by the TISCI Get_SoC_UID() function mentioned in Dominic's response (this is a unique ID per device). The MAC_IDx registers are read/write but will always reset to the unique default efuse value upon SoC reset.

Dominic,

Apologies for any confusion from the previous response. Yes, this SoC UID can be used as a unique identifier.

Best Regards,

Zackary Fleenor

thank you for your help
