Is there OTP ROM supported for C6713B EMIF boot?

I want to use OTP ROM (One Time Programmable ROM) for C6713B EMIF boot.

If you know such an ROM, please show the model number.

Thank you.

    The use of the OTP ROM is because DSP does not rewrite ROM.

    Therefore, if there are other solutions, please show it with the device model number.
    For example, the Flash ROM which has something like "Write disable pin".

    Thank you.

    You can use any asynchronous memory device that meets the voltage requirements for this DSP. The timing requirements can be adjusted by the programmation of the DSP.

    The easiest solution would be to use the device that is used on the DSK6713 since drivers and examples are available for it. If you do not write to it, then perhaps you can use a device that is not designed as an OTP.

    Thank you for an answer.

    I use the NOR Flash.
    And I will not tie WE-pin of the NOR Flash to WE-pin of the DSP.

    Thank you.
