CAT25C11/03/05/09/17
Doc. No. 1017, Rev. J
Figure 7. WRSR Instruction Timing
DESIGN CONSIDERATIONS
The CAT25C11/03/05/09/17 powers up in a write dis-
able 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 CAT25C11/03/05/09/17 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 CAT25C11/03/
05/09/17, 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 CAT25C11/03/05/09/17 will be reset
when power is ramped back up. If this is not possible,
then, following a brown-out episode, the CAT25C11/
03/05/09/17 can be reset by refreshing the contents of
the Status Register (See Application Note AN10).
