5. Device Addressing
The 1024K EEPROM requires an 8-bit device address word following a start condition to enable
the chip for a read or write operation (see Figure 7-1 on page 11 ). The device address word con-
sists of a mandatory one, zero sequence for the first four most significant bits as shown. This is
common to all two-wire EEPROM devices.
The 1024K uses the two device address bit, A1, A2, to allow up to four devices on the same bus.
These A1, A2 bits must compare to the corresponding hardwired input pins. The A1, A2 pin uses
an internal proprietary circuit that biases it to a logic low condition if the pin is allowed to float.
The seventh bit (P 0 ) of the device address is a memory page address bit. This memory page
address bit is the most significant bit of the data word address that follows. The eighth bit of the
device address is the read/write operation select bit. A read operation is initiated if this bit is high
and a write operation is initiated if this bit is low.
Upon a compare of the device address, the EEPROM will output a zero. If a compare is not
made, the device will return to a standby state.
