Operating supply voltage V
Prior to selecting the memory and issuing instructions to it, a valid and stable V
within the specified [V
secure a stable DC supply voltage, it is recommended to decouple the V
suitable capacitor (usually of the order of 10 nF to 100 nF) close to the V
pins.
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
When the power supply is turned on, V
vary faster than 1 V/µs.
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
instruction until V
lower than the minimum V
the POR threshold, the device is reset and is in Standby Power mode.
In a similar way, during power-down (continuous decrease in V
below the Power On Reset threshold voltage, the device stops responding to any instruction
sent to it.
Power-down conditions
During power-down (continuous decrease in V
mode (mode reached after decoding a Stop condition, assuming that is there is no internal
Write cycle in progress).
