Two-wire Serial EEPROM

Device Addressing
The 128K/256K EEPROM device require an 8-bit device address word following a start condition to
enable the chip for a read or write operation (refer to Figure 7).
The device address word consists of a mandatory one, zero sequence for the first four most
significant bits as shown. This is common to all the EEPROM devices.
The 128/256K EEPROM use the three device address bits A2, A1, A0 to allow as many as eight
devices on the same bus. These bits must compare to their corresponding hard-wired input pins. The
A2,A1 and A0 pins use an internal proprietary circuit that biases them to a logic low condition if the pins
are allowed to float.
The Module package device address word also consists of a mandatory one, zero sequence for the
first four most significant bits. The next 3 bits are all zero.
The eight 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.
Noise protection:
Special internal circuitry place on the SDA and SCL pins prevent small noise spikes from activating the
device.
Date Security:
The ACE24C128/256 has a hardware data protect scheme that slows the user to write protect the
entire memory when the WP pin is at Vcc.
Write Operations
Byte Write:
A write operation requires two 8-bit data word address following the device address word and
acknowledgment. Upon receipt of this address, the EEPROM will again respond with a zero and then
clock in the first 8-bit data word. Following receipt of the 8-bit data word, the EEPROM will output a
zero and the addressing device, such as a microcontroller, must terminate the write sequence with a
stop condition. At this time the EEPROM enters an internally timed write cycle, tWR, to the nonvolatile
memory. All inputs are disabled during this write cycle and the EEPROM will not respond until the write
is complete (refer to Figure 8).
