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 1.3V. WP pin provides hardware protection and is recommended to be kept at
V
mand sequences as shown in Figure 16. The two step command sequence for program/erase provides additional software protec-
tion.
