    Hi Denny,

    I apologize for any confusion, but could you please elaborate on what you mean by programming times if I am unable to answer the question in the following paragraph? 

    As far as programming the part goes, the PMBus interface supports 3 frequencies (100kHz, 400kHz, and 1 MHz). These are the frequencies and subsequent programming timings that the device supports.

    Regards,

    Hi Alec 

    Sorry make you confusion. The customer means time number of times which be burned.

    EX is asking the programming times/cycles TPS549D22 can support.

    I mean maybe that TPS549D22’s NVM can only be written 5,000 cycles/times, then, that NVM will can’t be written any more.

    EX wants to know this number of cycles.

    Does the memory register have a limit on the number of cycle it can be burned?

    Many thanks

    Denny

    Hi Denny,

    There is no limitation to the number of times the NVM of the device can be reprogrammed.
