Does anyone know how many times can reprogam the program flash in controller mentioned in subject?
I was kind of curious about that too. I didn't find any information about that in the datasheet. Besides, it says 'preliminary.' - mike
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. Erik
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.
