HY29F800
WE# = VIH. To initiate a write cycle, CE# and WE#
must be a logical zero while OE# is a logical one.
Sector Protection
Additional data protection is provided by the
HY29F800’s sector protect feature, described pre-
viously, which can be used to protect sensitive
areas of the Flash array from accidental or unau-
thorized attempts to alter the data.
Power-Up Write Inhibit
If WE# = CE# = VIL and OE# = VIH during power
up, the device does not accept commands on the
rising edge of WE#. The internal state machine is
automatically reset to the Read mode on power-
up.
