Supply voltage (V
This pin can be connected to an external DC supply voltage.
An internal voltage regulator allows the external voltage applied on V
M24LR16E-R, while preventing the internal power supply (rectified RF waveforms) to output
a DC voltage on the V
Operating supply voltage V
Prior to selecting the memory and issuing instructions to it, a valid and stable V
within the specified [V
maintain a stable DC supply voltage, it is recommended to decouple the V
suitable capacitor (usually of the order of 10 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 I²C write cycle (t
Power-up conditions
When the power supply is turned on, V
vary faster than 1V/µs.
Device reset in I²C mode
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
I²C instruction until V
lower than the minimum V
over the POR threshold, the device is reset and enters the Standby power mode. However,
the device must not be accessed until V
within the specified [V
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 decay of V

cycle in progress).
