Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the
absolute maximum ratings.

1. I2C BUS Data Communication
I2C BUS data communication starts by start condition input, and ends by stop condition input. Data is always 8bit long,
2
and acknowledge is always required after each byte. I C BUS data communication with several devices is possible by
connecting with 2 communication lines: serial data (SDA) and serial clock (SCL).
Among the devices, there should be a “master” that generates clock and control communication start and end. The
rest become “slave” which are controlled by an address peculiar to each device, like this EEPROM. The device that
outputs data to the bus during data communication is called “transmitter”, and the device that receives data is called
“receiver”.

2. Start Condition (Start Bit Recognition)
(1) Before executing each command, start condition (start bit) where SDA goes from 'HIGH' down to 'LOW' when
SCL is 'HIGH' is necessary.
(2) This IC always detects whether SDA and SCL are in start condition (start bit) or not, therefore, unless this
condition is satisfied, any command cannot be executed.
3. Stop Condition (Stop Bit Recognition)
(1) Each command can be ended by a stop condition (stop bit) where SDA goes from 'LOW' to 'HIGH' while SCL is
'HIGH'.
4. Acknowledge (ACK) Signal
(1) This acknowledge (ACK) signal is a software rule to show whether data transfer has been made normally or not.
In master-slave communication, the device (Ex. µ-COM sends slave address input for write or read command to
this IC) at the transmitter (sending) side releases the bus after output of 8bit data.
(2) The device (Ex. This IC receives the slave address input for write or read command from the µ-COM) at the
receiver (receiving) side sets SDA 'LOW' during 9th clock cycle, and outputs acknowledge signal (ACK signal)
showing that it has received the 8bit data.
(3) This IC, after recognizing start condition and slave address (8bit), outputs acknowledge signal (ACK signal)
'LOW'.
(4) After receiving 8bit data (word address and write data) during each write operation, this IC outputs acknowledge
signal (ACK signal) ‘LOW’.
(5) During read operation, this IC outputs 8bit data (read data) and detects acknowledge signal (ACK signal) 'LOW'.
When acknowledge signal (ACK signal) is detected, and stop condition is not sent from the master (µ-COM)
side, this IC continues to output data. When acknowledge signal (ACK signal) is not detected, this IC stops data
transfer, recognizes stop condition (stop bit), and ends read operation. Then this IC becomes ready for another
transmission.
5. Device Addressing
(1) Slave address comes after start condition from master.
(2) The significant 4 bits of slave address are used for recognizing a device type.
The device code of this IC is fixed to '1010'.
(3) The most insignificant bit ( R / W --- READ/ WRITE ) of slave address is used for designating write or read
operation, and is as shown below.
Setting R / W to 0 ------- write (setting 0 to word address setting of random read)
Setting R / W to 1 ------- read

Write Command
1. Write Cycle
(1) Arbitrary data can be written to this EEPROM. When writing only 1 byte, Byte Write is normally used, and when

During internal write execution, all input commands are ignored, therefore ACK is not returned.
Data is written to the address designated by word address (n-th address)
By issuing stop bit after 8bit data input, internal write to memory cell starts.
When internal write is started, command is not accepted for tWR (5ms at maximum).
Using page write cycle, writing in bulk is done as follows: When data of more than 16 Bytes is sent, the bytes in
excess overwrite the data already sent first.
(Refer to "Internal Address Increment".)
(7) As for page write cycle of BR24G16-3, where 2 or more bytes of data is intended to be written, after the page
select bits ‘P0’, ‘P1’, and ‘P2’ of slave address are designated arbitrarily, only the value of 4 least significant bits
in the address is incremented internally, so that data up to 16 bytes of memory only can be written.
1 page=16 Bytes, but the page write cycle time is 5ms at maximum for 16 Byte bulk write.
It does not stand 5ms at maximum x 16 Byte=80ms (max).

3. Write Protect (WP) Terminal
Write Protect (WP) Function
When WP terminal is set at Vcc (H level), data rewrite of all addresses is prohibited. When it is set GND (L level),
data rewrite of all address is enabled. Be sure to connect this terminal to Vcc or GND, or control it to H level or L
level. Do not leave it open.
In case of using it as ROM, it is recommended to connect it to pull up or Vcc. At extremely low voltage at power
ON/OFF, by setting the WP terminal ‘H’, write error can be prevented.

Read Command
1. Read Cycle
Read cycle is when data of EEPROM is read. Read cycle could be random read cycle or current read cycle. Random
read cycle is a command to read data by designating a specific address, and is used generally. Current read cycle is a
command to read data of internal address register without designating an address, and is used when to verify just after
write cycle. In both the read cycles, sequential read cycle is available where the next address data can be read in
succession.

Figure 39. Sequential Read Cycle (in the case of Current Read Cycle)
(1) In random read cycle, data of designated word address can be read.
(2) When the command just before current read cycle is random read cycle, current read cycle (each including
sequential read cycle), data of incremented last read address (n)-th, i.e., data of the (n+1)-th address is output.
(3) When ACK signal 'LOW' after D0 is detected, and stop condition is not sent from master (µ-COM) side, the next
address data can be read in succession.
(4) Read cycle is ended by stop condition where 'H' is input to ACK signal after D0 and SDA signal goes from ‘L’ to
‘H’ while SCL signal is 'H'.
(5) When 'H' is not input to ACK signal after D0, sequential read gets in, and the next data is output.
Therefore, read command cycle cannot be ended. To end read command cycle, be sure to input 'H' to ACK
signal after D0, and the stop condition where SDA goes from ‘L’ to ‘H’ while SCL signal is 'H'.
(6) Sequential read is ended by stop condition where 'H' is input to ACK signal after arbitrary D0 and SDA is
asserted from ‘L’ to ‘H’ while SCL signal is 'H'.

Software Reset
Software reset is executed to avoid malfunction after power ON, and during command input. Software reset has several
kinds, and 3 kinds of them are shown in the figure below. (Refer to Figure 40-(a), Figure 40-(b), Figure 40-(c).) Within the
dummy clock input area, the SDA bus is released ('H' by pull up) and ACK output and read data '0' (both 'L' level) may be
output from EEPROM. Therefore, if 'H' is input forcibly, output may conflict and over current may flow, leading to
instantaneous power failure of system power source or influence upon devices.

Acknowledge Polling
During internal write execution, all input commands are ignored, therefore ACK is not returned. During internal automatic
write execution after write cycle input, next command (slave address) is sent. If the first ACK signal sends back 'L', then it
means end of write operation, else 'H' is returned, which means writing is still in progress. By the use of acknowledge
polling, next command can be executed without waiting for tWR = 5ms.
To write continuously, R / W = 0, then to carry out current read cycle after write, slave address with R / W = 1 is sent, and
if ACK signal sends back 'L', then execute word address input and data output and so forth.
During internal write,
ACK = HIGH is returned.

WP Valid Timing (Write Cancel)
WP is usually fixed to 'H' or 'L', but when WP is used to cancel write cycle and so on, pay attention to the following WP valid
timing. During write cycle execution, inside cancel valid area, by setting WP='H', write cycle can be cancelled. In both byte
write cycle and page write cycle, the area from the first start condition of command to the rise of clock to take in D0 of
data(in page write cycle, the first byte data) is the cancel invalid area.
WP input in this area becomes ‘Don't care’. The area from the rise of SCL to take in D0 to the stop condition input is the
cancel valid area. Furthermore, after the execution of forced end by WP, the IC enters standby status.

Command Cancel by Start Condition and Stop Condition
During command input, by continuously inputting start condition and stop condition, command can be cancelled. (Figure
43.) However, within ACK output area and during data read, SDA bus may output 'L'. In this case, start condition and stop
condition cannot be input, so reset is not available. Therefore, execute software reset. When command is cancelled by
start-stop condition during random read cycle, sequential read cycle, or current read cycle, internal setting address is not
determined. Therefore, it is not possible to carry out current read cycle in succession. To carry out read cycle in succession,
carry out random read cycle.

I/O Peripheral Circuit
1. Pull-Up Resistance of SDA Terminal
SDA is NMOS open drain, so it requires a pull up resistor. As for this resistor value (RPU), select an appropriate value
from microcontroller VIL, IL, and VOL-IOL characteristics of this IC. If RPU is large, operating frequency is limited. The
smaller the RPU, the larger is the supply current (Read).
2. Maximum Value of RPU
The maximum value of RPU is determined by the following factors:
(1)SDA rise time to be determined by the capacitance (CBUS) of bus line and RPU of SDA should be tR or lower.
Furthermore, AC timing should be satisfied even when SDA rise time is slow.
(2)The bus’ electric potential ○
A to be determined by the input current leak total (IL) of the device connected to the bus
with output of 'H' to the SDA line and RPU should sufficiently secure the input 'H' level (VIH) of microcontroller and
EEPROM including recommended noise margin of 0.2Vcc.

Therefore, the condition (2) is satisfied.
4. Pull-Up Resistance of SCL Terminal
When SCL control is made at the CMOS output port, there is no need for a pull up resistor. But when there is a time
where SCL becomes 'Hi-Z', add a pull up resistor. As for the pull up resistor value, one of several kΩ to several ten kΩ is
recommended in consideration of drive performance of output port of microcontroller.

Cautions on Microcontroller Connection
1. RS
In I2C BUS, it is recommended that SDA port is of open drain input/output. However, when using CMOS input / output of
tri state to SDA port, insert a series resistance RS between the pull up resistor RPU and the SDA terminal of EEPROM.
This is to control over current that may occur when PMOS of the microcontroller and NMOS of EEPROM are turned ON
simultaneously. RS also plays the role of protecting the SDA terminal against surge. Therefore, even when SDA port is
open drain input/output, RS can be used.

2. Maximum Value of Rs
The maximum value of RS is determined by the following relations:
(1) SDA rise time to be determined by the capacitance (CBUS) of bus line and RPU of SDA should be tR or lower.
Furthermore, AC timing should be satisfied even when SDA rise time is slow.
(2) The bus’ electric potential ○
A to be determined by RPU and RS the moment when EEPROM outputs 'L' to SDA bus

The minimum value of Rs is determined by over current at bus collision. When over current flows, noises in power source
line and instantaneous power failure of power source may occur. When allowable over current is defined as I, the
following relation must be satisfied. Determine the allowable current in consideration of the impedance of power source

Power-Up/Down Conditions
At power on, the IC’s internal circuits may go through unstable low voltage area as the Vcc rises, making the IC’s internal
logic circuit not completely reset, hence, malfunction may occur. To prevent this, the IC is equipped with POR circuit and
LVCC circuit. To assure the operation, observe the following conditions at power ON.
1. Set SDA = 'H' and SCL ='L' or 'H’
2. Start power source so as to satisfy the recommended conditions of tR, tOFF, and Vbot for operating POR circuit.

Low Voltage Malfunction Prevention Function
LVCC circuit prevents data rewrite operation at low power, and prevents write error. At LVCC voltage (Typ=1.2V) or below,
data rewrite is prevented.
Noise Countermeasures
1. Bypass Capacitor
When noise or surge gets in the power source line, malfunction may occur, therefore, it is recommended to connect a
bypass capacitor (0.1µF) between the IC’s VCC and GND pins. Connect the capacitor as close to the IC as possible. In
addition, it is also recommended to connect a bypass capacitor between board’s VCC and GND.

Operational Notes
1.
Reverse Connection of Power Supply
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power
supply pins.
2.
Power Supply Lines
Design the PCB layout pattern to provide low impedance supply lines. Furthermore, connect a capacitor to ground at
all power supply pins. Consider the effect of temperature and aging on the capacitance value when using electrolytic
capacitors.
3.
Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
4.
Ground Wiring Pattern
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal
ground caused by large currents. Also ensure that the ground traces of external components do not cause variations
on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.
5.
Thermal Consideration
Should by any chance the maximum junction temperature rating be exceeded the rise in temperature of the chip may
result in deterioration of the properties of the chip. In case of exceeding this absolute maximum rating, increase the
board size and copper area to prevent exceeding the maximum junction temperature rating.
6.
Recommended Operating Conditions
These conditions represent a range within which the expected characteristics of the IC can be approximately
obtained. The electrical characteristics are guaranteed under the conditions of each parameter.
7.
Inrush Current
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may
flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power
supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring,
and routing of connections.
8.
Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
9.
Testing on Application Boards
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply
should always be turned off completely before connecting or removing it from the test setup during the inspection
process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during
transport and storage.
10. Inter-pin Short and Mounting Errors
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in
damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment)
and unintentional solder bridge deposited in between pins during assembly to name a few.
11. Unused Input Pins
Input pins of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance and
extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small
charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and
cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the
power supply or ground line.
12. Regarding the Input Pin of the IC
In the construction of this IC, P-N junctions are inevitably formed creating parasitic diodes or transistors. The
operation of these parasitic elements can result in mutual interference among circuits, operational faults, or physical
damage. Therefore, conditions which cause these parasitic elements to operate, such as applying a voltage to an
input pin lower than the ground voltage should be avoided. Furthermore, do not apply a voltage to the input pins
when no power supply voltage is applied to the IC. Even if the power supply voltage is applied, make sure that the
input pins have voltages within the values specified in the electrical characteristics of this IC.
