Notes: 1. This does not include the preprogramming time.
2. This timing is for Sector Protection Operation.
3. The time between writes must be less than “tTOW” otherwise that command will not be accepted and
erasure will start. A time-out or “tTOW” from the rising edge of last CE or WE whichever happens first will
initiate the execution of the Sector Erase command(s).
4. When the Erase Suspend command is written during the Sector Erase operation, the device will take a
maximum of “tSPD” to suspend the erase operation.
