DESIGN CONSIDERATIONS
The CAT250140/20/40 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 CAT250140/20/40 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,

HIGH IMPEDANCE
SO is in a high impedance. If an invalid op code is
received, no data will be shifted into the CAT250140/
20/40, 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 CAT250140/20/40 will be reset when
power is ramped back up. If this is not possible, then,
following a brown-out episode, the CAT250140/20/40
can be reset by refreshing the contents of the Status
Register (See Application Note AN10).
