TMS320F2806: Uniqueness of TMS320F2806PZS

Faith Luo
Intellectual 500 points

Part Number: TMS320F2806

Dear Sir：


I wonder know if I can get value of the register or other information that can represent the uniqueness of a chip(TMS320F2806PZS).

We want to use this to make a version of the firmware available only one chip(TMS320F2806PZS)，which will protect our source code from being copied by customers and burn directly to other chips.

Thank you very much.

    Faith,

    There is a PARTID register which records the device type:
    0x002C - F2801
    0x0024 – F2802
    0x0034 – F2806
    0x003C – F2808
    0x00FE – F2809
    0x0014 – F28016
    0x001C – F28015
    0xFF2C – C2801
    0xFF24 – C2802


    The REVID register will give you the silicon revision. See p.41 of the datasheet for more information:
    www.ti.com/.../tms320f2808.pdf

    However if you need an absolute unique number for each IC, I regret to say there isn't anything like that on F280x, though it does exist on newer devices such as F2837x. Sorry not to have better news.

    Regards,

    Richard
