Pin Function  
Serial Clock (SCL)  
The SCL pin is used to control serial input/output data timing. The SCL input is used to positive edge  
clock data into EEPROM device and negative edge clock data out of each device. Maximum clock rate is  
400 kHz.  
Serial Input/Output Data (SDA)  
The SDA pin is bidirectional for serial data transfer. The SDA pin needs to be pulled up by resistor as that  
pin is open-drain driven structure. Use proper resistor value for your system by considering VOL, IOL and  
the SDA pin capacitance. Except for a start condition and a stop condition which will be discussed later,  
the SDA transition needs to be completed during the SCL low period.

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

Functional Description  
Start Condition  
A high-to-low transition of the SDA with the SCL high is needed in order to start read, write operation  
(See start condition and stop condition).  
Stop Condition  
A low-to-high transition of the SDA with the SCL high is a stop condition. The stand-by operation starts  
after a read sequence by a stop condition. In the case of write operation, a stop condition terminates the  
write data inputs and place the device in a internally-timed write cycle to the memories. After the  
internally-timed write cycle which is specified as tWC, the device enters a standby mode (See write cycle  
timing).

Acknowledge  
All addresses and data words are serially transmitted to and from in 8-bit words. The receiver sends a  
zero to acknowledge that it has received each word. This happens during ninth clock cycle. The  
transmitter keeps bus open to receive acknowledgment from the receiver at the ninth clock. In the write  
operation, EEPROM sends a zero to acknowledge after receiving every 8-bit words. In the read operation,  
EEPROM sends a zero to acknowledge after receiving the device address word. After sending read data,  
the EEPROM waits acknowledgment by keeping bus open. If the EEPROM receives zero as an  
acknowledge, it sends read data of next address. If the EEPROM receives acknowledgment "1" (no  
acknowledgment) and a following stop condition, it stops the read operation and enters a stand-by mode.  
If the EEPROM receives neither acknowledgment "0" nor a stop condition, the EEPROM keeps bus open  
without sending read data.

Device Addressing  
The EEPROM device requires an 8-bit device address word following a start condition to enable the chip  
for a read or a write operation. The device address word consists of 4-bit device code, 3-bit device  
address code and 1-bit read/write(R/W) code. The most significant 4-bit of the device address word are  
used to distinguish device type and this EEPROM uses “1010” fixed code. The device address word is  
followed by the 3-bit device address code in the order of A2, A1, A0. The device address code selects one  
device out of all devices which are connected to the bus. This means that the device is selected if the  
inputted 3-bit device address code is equal to the corresponding hard-wired A2-A0 pin status. The  
eighth bit of the device address word is the read/write(R/W) bit. A write operation is initiated if this bit is  
low and a read operation is initiated if this bit is high. Upon a compare of the device address word, the  
EEPROM enters the read or write operation after outputting the zero as an acknowledge. The EEPROM  
turns to a stand-by state if the device code is not “1010” or device address code doesn’t coincide with  
status of the correspond hard-wired device address pins A0 to A2.

Write Operations  
Byte Write:  
A write operation requires an 8-bit device address word with R/W = “0”. Then the EEPROM sends  
acknowledgment "0" at the ninth clock cycle. After these, the 32kbit EEPROM receives 2 sequence 8-bit  
memory address words. Upon receipt of this memory address, the EEPROM outputs acknowledgment "0"  
and receives a following 8-bit write data. After receipt of write data, the EEPROM outputs  
acknowledgment "0". If the EEPROM receives a stop condition, the EEPROM enters an internally-timed  
write cycle and terminates receipt of SCL, SDA inputs until completion of the write cycle. The EEPROM  
returns to a standby mode after completion of the write cycle.

Page Write:  
The EEPROM is capable of the page write operation which allows any number of bytes up to 32 bytes to  
be written in a single write cycle. The page write is the same sequence as the byte write except for  
inputting the more write data. The page write is initiated by a start condition, device address word,  
memory address(n) and write data (Dn) with every ninth bit acknowledgment. The EEPROM enters the  
page write operation if the EEPROM receives more write data (Dn+1) instead of receiving a stop  
condition. The a0 to a4 address bits are automatically incremented upon receiving write data (Dn+1).  
The EEPROM can continue to receive write data up to 32 bytes. If the a0 to a4 address bits reaches the  
last address of the page, the a0 to a4 address bits will roll over to the first address of the same page and  
previous write data will be overwritten. Upon receiving a stop condition, the EEPROM stops receiving  
write data and enters internally-timed write cycle.

Acknowledge Polling:  
Acknowledge polling feature is used to show if the EEPROM is in a internally-timed write cycle or not.  
This feature is initiated by the stop condition after inputting write data. This requires the 8-bit device  
address word following the start condition during a internally-timed write cycle. Acknowledge polling  
will operate when the R/W code = “0”. Acknowledgment “1” (no acknowledgment) shows the EEPROM  
is in a internally-timed write cycle and acknowledgment “0” shows that the internally-timed write cycle has  
completed. See Write Cycle Polling using ACK.

Read Operation  
There are three read operations: current address read, random read, and sequential read. Read operations  
are initiated the same way as write operations with the exception of R/W = “1”.  
Current Address Read:  
The internal address counter maintains the last address accessed during the last read or write operation,  
with incremented by one. Current address read accesses the address kept by the internal address counter.  
After receiving a start condition and the device address word (R/W is “1”), the EEPROM outputs the 8-bit  
current address data from the most significant bit following acknowledgment “0”. If the EEPROM  
receives acknowledgment “1” (no acknowledgment) and a following stop condition, the EEPROM stops  
the read operation and is turned to a standby state. In case the EEPROM has accessed the last address of  
the last page at previous read operation, the current address will roll over and returns to zero address. In  
case the EEPROM has accessed the last address of the page at previous write operation, the current address  
will roll over within page addressing and returns to the first address in the same page. The current address  
is valid while power is on. The current address after power on will be indefinite. The random read  
operation described below is necessary to define the memory address.

Random Read:  
This is a read operation with defined read address. A random read requires a dummy write to set read  
address. The EEPROM receives a start condition, device address word (R/W=0) and memory address 2 ×  
8-bit sequentially. The EEPROM outputs acknowledgment “0” after receiving memory address then  
enters a current address read with receiving a start condition. The EEPROM outputs the read data of the  
address which was defined in the dummy write operation. After receiving acknowledgment “1”(no  
acknowledgment) and a following stop condition, the EEPROM stops the random read operation and  
returns to a standby state.

Sequential Read:  
Sequential reads are initiated by either a current address read or a random read. If the EEPROM receives  
acknowledgment “0” after 8-bit read data, the read address is incremented and the next 8-bit read data are  
coming out. This operation can be continued as long as the EEPROM receives acknowledgment “0”.  
The address will roll over and returns address zero if it reaches the last address of the last page. The  
sequential read can be continued after roll over. The sequential read is terminated if the EEPROM  
receives acknowledgment “1” (no acknowledgment) and a following stop condition.

Notes  
Data Protection at VCC On/Off  
When VCC is turned on or off, noise on the SCL and SDA inputs generated by external circuits (CPU, etc)  
may act as a trigger and turn the EEPROM to unintentional program mode. To prevent this unintentional  
programming, this EEPROM has a power on reset function. Be careful of the notices described below in  
order for the power on reset function to operate correctly.  
SCL and SDA should be fixed to VCC or VSS during VCC on/off. Low to high or high to low transition  
during VCC on/off may cause the trigger for the unintentional programming.  
VCC should be turned off after the EEPROM is placed in a standby state.  
V
CC should be turned on from the ground level(VSS) in order for the EEPROM not to enter the  
unintentional programming mode.  
VCC turn on speed should be longer than 10 µs.  
Noise Suppression Time  
This EEPROM have a noise suppression function at SCL and SDA inputs, that cut noise of width less than  
50 ns. Be careful not to allow noise of width more than 50 ns.
