WRITE/ERASE CYCLE ENDURANCE
and fabricated to meet advanced firmware storage
requirements. To ensure this level of reliability, V
must be at 5V ±10% during WRITE or ERASE cycles.
Due to process technology advances, 5V V

POWER USAGE
power-saving features that may be utilized in the array

When CE# is HIGH, the device enters standby mode. In
this mode, maximum I
is brought HIGH during a WRITE or ERASE, the ISM
continues to operate, and the device consumes the
respective active power until the WRITE or ERASE is
completed.
