Data Protection & Power up sequence
The device is designed to offer protection from any involuntary program/erase during power-transitions. An internal voltage detector
disables all functions whenever Vcc is below about 1.1V(1.8V device) or 2V(3.3V device). WP pin provides hardware protection and
is recommended to be kept at V
circuit gets ready for any command sequences as shown in Figure 18. The two step command sequence for program/erase provides
additional software protection.
