    Hi all,

    I found TI's 320 series DSP haven't on-chip Flash or on-chip ROM.
    For most of the MCU have on-chip Flash, the codes in the Flash are
    safty.
    But how to protect the code outside TI DSP?

    Any suggestions will be appreciated!

    Best regards,
    Davy

    Choose other chip with flash, for example tms320f2812.
    Copy Protection - High
    2)
    HASP!
    to add new chip to your schematic, with on-chip flash.
    Copy Protection - Low

    Hi Timber,

    Thank you for your help!

    1) I search "tms320f" in ti.com and found only c2000 series support
    on-chip ROM, is it right?

    2) May you please recommend some HASP solution?

    Any suggestions will be appreciated!
    Best regards,
    Davy

    look at column flash.
    Hardware of HASP:
    any microcontroller with on-chip flash (for example tms320f2812 or less).

    Firmware of HASP:
    Try put your "know-how" algorithm to flash...

    Its not support flash(flash is Reprogrammable ROM :) ).

    On-chip ROM is too expensive feature, commonly...

    ROM is used at the order of the big party of chips.
    You transfer your firmware to the manufacturer and he stamps chips with
    your firmware.
