8. Trap: E²PROM 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 E²PROM receives the stop condition signal compulsorily, during receiving 1 byte of write data,
“write” operation is aborted.
When the E²PROM 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: E²PROM 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-24CS64A
(which can be executed 32-byte page write) is received data more than 33 byte, 8-bit data of the 33rd 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 max ratings, as listed on
the data sheet. Exceeding the supply voltage rating can cause latch-up.
Operations with moisture on the E²PROM pins may occur malfunction by short-circuit between pins.
Especially, in occasions like picking the E²PROM up from low temperature tank during the evaluation. Be
sure that not remain frost on E²PROM 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.
