X28LV010
Characteristics subject to change without notice.
6 of 18
The X28LV010 can be automatically protected during
power-up and power-down without the need for exter-
nal circuits by employing the software data protection
feature. The internal software data protection circuit is
enabled after the first write operation utilizing the soft-
ware algorithm. This circuit is nonvolatile and will
remain set for the life of the device unless the reset
command is issued.
Once the software protection is enabled, the X28LV010
is also protected from inadvertent and accidental
writes in the powered-up state. That is, the software
algorithm must be issued prior to writing additional
data to the device.
SOFTWARE ALGORITHM
Selecting the software data protection mode requires
the host system to precede data write operations by a
series of three write operations to three specific
addresses. Refer to Figures 6 and 7 for the sequence.
The three byte sequence opens the page write window
enabling the host to write from one to two hundred fifty-
six bytes of data. Once the page load cycle has been
completed, the device will automatically be returned to
the data protected state.
