    Question:
    How can I get the silicon unique ID of PSoC® device?

    Answer:

    The PSoC Creator and ModusToolbox® offer us system functions to acquire the unique ID.

    PSoC 3, PSoC 4, and PSoC 5LP call the API: void CyGetUniqueId(uint32* uniqueId).

    PSoC 6 calls the API: uint64_t Cy_SysLib_GetUniqueId(void).

    The ID includes Die lot, Die Wafer, Die X, Die Y, Die Sort, Die Minor, and Die Year.

     

    Note: The uniqueness of the number is guaranteed for 10 years due to the die lot number having a 10-year lifecycle; even after 10 years, the probability of getting two identical numbers is very small.
