Write Protect (W)
This input signal is used to control whether the memory is write protected. When Write
Protect (W) is held low, writes to the memory are disabled, but other operations remain
enabled. Write Protect (W) must either be driven high or low, but must not be left floating.

order to secure a stable DC supply voltage, it is recommended to decouple the V
a suitable capacitor (usually of the order of 10 nF to 100 nF) close to the V
pins.
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 V
reaches the internal reset threshold voltage (this threshold is defined in
