... Figure 20 Address Increment Timing in Writing Write Inhibition Function at Low Power Voltage The S-24CS01A/02A/04A/08A have a detection circuit for low power voltage. The detection circuit cancels a write instruction when the power voltage is low or the power switch is on. The detection voltage is 1.75 V typically and the release voltage is 2.05 V typically, the hysteresis of approximate 0.3 V thus exists. (See Figure 21 ...
