Operating supply voltage (V
Prior to selecting the memory and issuing instructions to it, a valid and stable V
within the specified [V
DC supply voltage, it is recommended to decouple the V
(usually of the order of 10 nF to 100 nF) close to the V
This voltage must remain stable and valid until the end of the transmission of the instruction
and, for a Write instruction, until the completion of the internal write cycle (t
Power-up conditions

Power-up and device reset
In order to prevent inadvertent Write operations during power-up, a power on reset (POR)
circuit is included. At power-up (continuous rise of V

Power-down
At power-down (continuous decrease in V
operating voltage to below the power on reset threshold voltage, the device stops
responding to any instruction sent to it.
During power-down, the device must be deselected and in the Standby Power mode (that is,
there should be no internal Write cycle in progress).
