The S-24C128C does the write operation only when it receives data of 1 byte or more and receives a stop
condition immediately after ACK output.
Refer to Figure 30 regarding details.
By a start condition, users are able to cancel command which is being input. However, adjust the phase while the
S-24C128C is outputting “L” because users are not able to input a start condition. When users cancel the
command, there may be a case that the address will not be identified. Use random read for the read operation, not
current address read.
● Absolute maximum ratings: Do not operate these ICs in excess of the absolute maximum ratings (as listed on
● Operations with moisture on the S-24C128C pins may occur malfunction by short-circuit between pins.

the data sheet). Exceeding the supply voltage rating can cause latch-up.
Especially, in occasions like picking the S-24C128C up from low temperature tank during the evaluation. Be
sure that not remain frost on the S-24C128C’s pins to prevent malfunction by short-circuit.
Also attention should be paid in using on environment, which is easy to dew for the same reason.
