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
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.
Pin Connections for A0 to A2
Notes: 1. “V
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. WP pin should be fixed high or low
status from start condition input to stop condition input. The read operation is always activated irrespective of the WP
pin status.
