Notes: ? Use either of CE1 or CE2, or both for disable control of the device.
? Because turning the power-on from an intermediate level cause malfunction, when the
power is turned on, V CC is required to be started from 0 V.
? If the device does not operate within the specified conditions of read cycle, write cycle,
power on/off sequence, memory data can not be guaranteed.
? When turning the power on or off, it is recommended that CE2 is connected to ground to
prevent unexpected writing.
