Device Address
(A0, A1, A2)
UP to eight devices for 2k, four devices for 4k, can be addressed on the same bus by setting the levels on
these pins to different combinations. The levels on these pins are compared with the device address code
which are input through the SDA pin. The device is selected if the compare is successfully done. These
pins are internally pulled-down to V
SS
. The device read these pins as Low if unconnected. As for 4k, it is
unneccesary for the A0 pin to be connected because the corresponding device address code is used as
memory address a8.

Write Protect
(WP)
When the Write Protect pin (WP) is high, the write protections feature is enabled and operates as shown in
the following table. When the WP is low, write operations for all memory array are allowed. The read
operation is always activated irrespective of the WP pin status. The WP pin is internally pull-down to V
SS
.
Write operations for all memory array are allowed if unconnected.
