DATA PROTECTION
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 2V. WP pin provides hardware protection and is recommended to be kept at V
during power-up and power-down as shown in Figure 11. The two step command sequence for program/erase provides additional
software protection.
