Device Overview

(5) Current fluctuation (Typ.) at +5 V when power is turned on

Figure 1.2 Current fluctuation (Typ.) at +5 V when power is turned on

(6) Power on/off sequence

The voltage detector circuits monitor +5 V. The circuits do not allow a write signal if either voltage is abnormal. These prevent data from being destroyed and eliminates the need to be concerned with the power on/off sequence.
