  • Just for reference I looked up the P89C51Rx2, the number is >10000. I do, however, remember the early flash days when you gave your development chips to production on a regular basis because the guarantee was 100 cycles. To the best of my recollection the numbers you see these days are 1000-10000 erase-reprogram cycles.

  • Hi Mike,

    it is mentioned 100 times to erase/write
    with a retension of 15 years.
    (depending on temperature)

    But that I would not take as serious, as our experiences show.

    This are conventional specs.

    We reprogrammed the devices more than this specifics and they works properly.
