我試了,超過8個就出錯,好像把前面寫的覆盖了!

不会,是你的程序有问题.

资料里写得很清楚

Write Operations BYTE WRITE: A write operation requires an 8-bit data word address following the
device address word and acknowledgment. Upon receipt of this address, the EEPROM
will again respond with a zero and then clock in the first 8-bit data word. Following
receipt of the 8-bit data word, the EEPROM will output a zero and the addressing
device, such as a microcontroller, must terminate the write sequence with a stop condition.
At this time the EEPROM enters an internally timed write cycle, tWR, to the
nonvolatile memory. All inputs are disabled during this write cycle and the EEPROM will
not respond until the write is complete (see Figure 8 on page 11).

PAGE WRITE: The 1K/2K EEPROM is capable of an 8-byte page write, and the 4K, 8K
and 16K devices are capable of 16-byte page writes.

24C01 24C02是8字节
24C04 24C08 24C16是16字节
