Device Address (A0, A1, A2)
Eight devices can be wired for one common data bus line as maximum. Device address pins are used to
distinguish each device and device address pins should be connected to V
code provided from SDA pin matches corresponding hard-wired device address pins A0 to A2, that one
device can be activated. As for 8k to 16k EEPROM, whole or some device address pins don't need to be
fixed since device address code provided from the SDA pin is used as memory address signal.

Write Protect (WP)
When the Write Protect pin (WP) is high, the write protection feature is enabled and operates as shown in
the following table. When the WP is low, write operation for all memory arrays are allowed. The read
operation is always activated irrespective of the WP pin status. WP should be fixed high or low during
operations since WP does not provide a latch function.
