8. Address Increment Timing
The timing for the automatic address increment is the falling edge of the SCL clock for the 8th bit of the
read data in read operation and the falling edge of the SCL clock for the 8th bit of the received data in write
operation.

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
.)
When a low power voltage is detected, a write instruction is canceled at the reception of a stop condition.
When the power voltage lowers during a data transmission or a write operation, the data at the address of
the operation is not assured.
