DESIGN CONSIDERATIONS
The CAT25C33/65 powers up in a write disable state
and in a low power standby mode. A WREN instruction
must be issued to perform any writes to the device after
power up. Also,on power up
CS
should be brought low
to enter a ready state and receive an instruction. After
a successful byte/page write or status register write the
be set high after the proper number of clock cycles to
start an internal write cycle. Access to the array during
an internal write cycle is ignored and program-ming
is continued. On power up, SO is in a high impedance.

When powering down, the supply should be taken down
to 0V, so that the CAT25C33/65 will be reset when power
is ramped back up. If this is not possible, then, following
a brown-out episode, the CAT25C33/65 can be reset by
refreshing the contents of the Status Register (See Appli-
cation Note AN10).
