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 1 MHz.
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 opendrain 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.

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. Also, acknowledgment "0" is outputted after inputting device address and memory address. After inputting write
data, acknowledgment "1"(NO ACK) is outputted.
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.

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 code is followed by the 3-bit device address code. 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(WP=Low)
Byte Write: (Write operation during WP=Low status)
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 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 128 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 a6 address bits are automatically incremented upon receiving
write data (Dn+1). The EEPROM can continue to receive write data up to 128 bytes. If the a0 to a6 address bits
reaches the last address of the page, the a0 to a6 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.

Notes: 1. 2nd device address code (#) should be same as 1st (@).
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.
• 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 rate should be slower than 2 µs/V.
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.
