hi,
i would like to know the write and erase times for a sector for a 89V51RD2 microcontroller. if you have this info please share it.
Also i see from the datasheet that the write/erase cycles are 10000. is this for one sector or for the entire block? the origin of this question is can the lifetime of the device be calculated as
lifetime of flash = 10000 * number of sectors ?
i will use one sector at a time and then when this sector is full erase and begin writing again to this sector. when the number of write/erase cycles are over then i move over to the next sector. will this work?
any inputs will be helpful. thanks in advance.
Normally, writes are fast. It's normally the erase to make the flash sector ready to accept data that takes lots of time. Which means that having one sector pre-erased can reduce your power needs - but if that write fails you lost your margin for a second attempt.
