10. Precaution for use
R
The S-24C04C 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 32 regarding details.

By a start condition, users are able to cancel command which is being input. However, adjust the phase while the S-
24C04C 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 the
data sheet). Exceeding the supply voltage rating can cause latch-up.
Operations with moisture on the S-24C04C pins may occur malfunction by short-circuit between pins. Especially, in
occasions like picking the S-24C04C up from low temperature tank during the evaluation. Be sure that not remain
frost on the S-24C04C pin to prevent malfunction by short-circuit.
Also attention should be paid in using on environment, which is easy to dew for the same reason.
