Data Protection

Power On State
The following protection has been implemented to
The 25XX160 powers on in the following state:
prevent inadvertent writes to the array:
? The write enable latch is reset on power-up
? A WRITE ENABLE instruction must be issued to
set the write enable latch
? After a byte write, page write, or Status register
write, the write enable latch is reset
? 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
?
?
?
?
The device is in low power Standby mode (CS = 1 )
The write enable latch is reset
SO is in high-impedance state
A low level on CS is required to enter active state
