2.7
Data Protection
The following protection has been implemented to
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
2.8
Power-On State
The 25XX128 powers on in the following state:
The device is in low-power Standby mode
(CS=
1
)
The write enable latch is reset
SO is in high-impedance state
A high-to-low-level transition on CS is required to
enter active state
