Signal description

2.5.4

Device reset

In order to prevent inadvertent write operations during power-up, a power-on-reset (POR)

circuit is included.

At power-up, the device does not respond to any instruction until VCC has reached the

internal reset threshold voltage. This threshold is lower than the minimum VCC operating

voltage (see Operating conditions in Section 8: DC and AC parameters). When VCC passes

over the POR threshold, the device is reset and enters the Standby Power mode; however,

the device must not be accessed until VCC reaches a valid and stable DC voltage within the

specified [VCC(min), VCC(max)] range (see Operating conditions in Section 8: DC and AC

parameters).

In a similar way, during power-down (continuous decrease in VCC), the device must not be

accessed when VCC drops below VCC(min). When VCC drops below the threshold voltage,

the device stops responding to any instruction sent to it.

Power-down conditions

During power-down (continuous decrease in VCC), the device must be in the Standby Power

mode (mode reached after decoding a Stop condition, assuming that there is no internal

write cycle in progress).
