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 64kbit 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 reads are initiated by either a current address read or a random read. If the EEPROM receives

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

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.
• VCC 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.

warranties or representations with respect to the accuracy or completeness of the information contained in this document nor grants any license to any intellectual property
rights or any other rights of Renesas or any third party with respect to the information in this document.

and regulations, and procedures required by such laws and regulations.
4. All information included in this document such as product data, diagrams, charts, programs, algorithms, and application circuit examples, is current as of the date this
document is issued. Such information, however, is subject to change without any prior notice. Before purchasing or using any Renesas products listed in this document,
please confirm the latest product information with a Renesas sales office. Also, please pay regular and careful attention to additional and different information to be
disclosed by Renesas such as that disclosed through our website. (http://www.renesas.com )
5. Renesas has used reasonable care in compiling the information included in this document, but Renesas assumes no liability whatsoever for any damages incurred as a
result of errors or omissions in the information included in this document.
6. When using or otherwise relying on the information in this document, you should evaluate the information in light of the total system before deciding about the applicability
of such information to the intended application. Renesas makes no representations, warranties or guaranties regarding the suitability of its products for any particular
application and specifically disclaims any liability arising out of the application and use of the information in this document or Renesas products.
7. With the exception of products specified by Renesas as suitable for automobile applications, Renesas products are not designed, manufactured or tested for applications
or otherwise in systems the failure or malfunction of which may cause a direct threat to human life or create a risk of human injury or which require especially high quality
and reliability such as safety systems, or equipment or systems for transportation and traffic, healthcare, combustion control, aerospace and aeronautics, nuclear power, or
undersea communication transmission. If you are considering the use of our products for such purposes, please contact a Renesas sales office beforehand. Renesas shall
have no liability for damages arising out of the uses set forth above.
8. Notwithstanding the preceding paragraph, you should not use Renesas products for the purposes listed below:
(1) artificial life support devices or systems
(2) surgical implantations
(3) healthcare intervention (e.g., excision, administration of medication, etc.)
(4) any other purposes that pose a direct threat to human life
Renesas shall have no liability for damages arising out of the uses set forth in the above and purchasers who elect to use Renesas products in any of the foregoing
applications shall indemnify and hold harmless Renesas Technology Corp., its affiliated companies and their officers, directors, and employees against any and all
damages arising out of such applications.

10. Although Renesas endeavors to improve the quality and reliability of its products, IC products have specific characteristics such as the occurrence of failure at a certain
rate and malfunctions under certain use conditions. Please be sure to implement safety measures to guard against the possibility of physical injury, and injury or damage
caused by fire in the event of the failure of a Renesas product, such as safety design for hardware and software including but not limited to redundancy, fire control and
malfunction prevention, appropriate treatment for aging degradation or any other applicable measures. Among others, since the evaluation of microcomputer software
