DESIGN CONSIDERATIONS
The CAT25C08/16 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
CAT25C08/16 goes into a write disable mode.
CS
must
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 programming is
continued. On power up, SO is in a high impedance. If
an invalid op code is received, no data will be shifted
into the CAT25C08/16, and the serial output pin (SO)
will remain in a high impedance state until the falling
edge of
CS
is detected again.
When powering down, the supply should be taken down
to 0V, so that the CAT25C08/16 will be reset when
power is ramped back up. If this is not possible, then,
following a brown-out episode, the CAT25C08/16 can
be reset by refreshing the contents of the Status Reg-
ister (See Application Note AN10).
