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 CC or V SS . When device address
code provided from SDA pin matches corresponding hard-wired device address pins A0 to A2, that one
device can be activated.

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.
Also, acknowledgment "0" is outputted after inputting device address and memory address. After
inputting write data, acknowledgment "1"" (NO ACK) is outputted.
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.
