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 SCL low period.

Note: High-to-low and low-to-high change of SDA should be done during SCL low periods.
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 V SS. When device address
code provided from SDA pin matches corresponding hard-wired device address pins A0 to A2, that one
device can be activated. As for 4k 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.

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. The read
operation is always activated irrespective of the WP pin status. WP should be fixed high or low during
operations since WP does not provide a latch function.

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. As for the 4kbit, 8kbit and
16kbit EEPROMs, whole or some bits of their device address code may be used as the memory address
bits. For example, A0 is used as a8 of memory address for the 4kbit, A0 and A1 are used as a8 and a9 for
the 8kbit. The 16kbit doesn't use the device address code instead all 3 bits are used as the memory address
bits a8, a9 and a10. 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 2kbit to 16kbit EEPROMs receive 8-bit
memory address word, on the other hand the 32kbit and 64kbit EEPROMs receive 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 features 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 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 have 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 have 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 (8-bit
for 2kbit to 16kbit EEPROMs, 2 × 8-bit for 32kbit and 64kbit EEPROMs) 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 have 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 us.
Write/Erase Endurance and Data retention Time
The endurance is 10 5 cycles in case of page programming and 104 cycles in case of byte programming (1%
cumulative failure rate). The data retention time is more than 10 years when a device is page-programmed
less than 104 cycles.
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.
