8. S-34C02A Operation when inputting a stop condition with the clock less than the defined data
length (less than 8-bit) to the SCL pin inputting Write data
If S-34C02A forcibly recieves a stop condition while it is receiving Write data of 1-byte, it does not perform the Write
operation.
To operate Page Write, if S-34C02A recieves a stop condition after receiving data of 1-byte or more, S-34C02A
operates Write only in the address equivalent to the byte of which S-34C02A normally received 8-bit data before a
stop condition.
9. S-34C02A Operation and data if inputting Write data more than the defined Page Size during Page
Write
The S-34C02A is able to Page Write of 16-byte, but in case if it receives data of 17-byte, 8-bit data of the 17th byte is
overwritten in the first byte in the same page because the S-34C02A cannot Write data across the page address.
10. Precaution for use
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 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 the 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.
