8. Trap: E

2PROM operation in case that the stop condition is received during write operation before

receiving the defined data value (less than 8-bit) to SCL pin

When the E

2PROM receives the stop condition signal compulsorily, during receiving 1 byte of write data,

“write” operation is aborted.

When the E

2PROM receives the stop condition signal after receiving 1 byte or more of data for “page

write”, 8-bit of data received normally before receiving the stop condition signal can be written.

9. Trap: E

2PROM operation and write data in case that write data is input more than defined page size at

“page write”

When write data is input more than defined page size at page write operation, for example, S-24CS04A

(which can be executed 16-byte page write) is received data more than 17 byte, 8-bit data of the 17th byte

is over written to the first byte in the same page. Data over the capacity of page address cannot be written.

10. Trap: Severe environments

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 E

2PROM pins may occur malfunction by short-circuit between pins.

Especially, in occasions like picking the E

2PROM up from low temperature tank during the evaluation. Be

sure that not remain frost on E

2PROM 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.
