2.5
VSS ground
VSS is the reference for the VCC supply voltage.
2.6
Supply voltage (VCC)
2.6.1
Operating supply voltage VCC
Prior to selecting the memory and issuing instructions to it, a valid and stable VCC voltage
Table 10). In order to secure a stable DC supply voltage, it is recommended to decouple the
VCC line with a suitable capacitor (usually of the order of 10 nF to 100 nF) close to the
VCC/VSS package 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 (tW).
2.6.2
Power-up conditions
and the rise time must not vary faster than 1 V/s.
2.6.3
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
reaches an internal reset threshold voltage. This threshold is lower than the minimum VCC
operating voltage defined in Table 8, Table 9 and Table 10.
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 VCC voltage within the specified [VCC(min), VCC(max)] range.
In a similar way, during power-down (continuous decrease in VCC), as soon as VCC drops
below the power on reset threshold voltage, the device stops responding to any instruction
sent to it.
2.6.4
Power-down conditions
During power-down (where VCC decreases continuously), 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).
