The S-24C08A/16A is a series of 2-wired, low power 8K/16K-bit
EEPROMs with a wide operating range. They are organized as 1K-word
8-bit, 2K-word 8-bit respectively. Each is capable of page write, and
sequential read.
The time for byte write and page write is the same, i. e., 1 msec. (max.)
during operation at 5 V 10%.

Pin Functions
1. Address Input Pins (A2)
Connect pins A2 to the GND or the V
CC
to assign slave addresses. There are 2 different ways to assign
slave addresses in the S-24C08A. The S-24C16A doesn't have address input, so the slave address
cannot be input. When the input slave address coincides with the slave address transmitted from the
master device, 1 device can be selected from among multiple devices connected to the bus. Always
connect the address input pin to GND or V
CC
and leave it unchanged.
2. SDA (Serial Data Input/Output) Pin
The SDA pin is used for bilateral transmission of serial data. It consists of a signal input pin and an Nch
open-drain transistor output pin.
Usually pull up the SDA line via resistance to the V
CC
, and use it with other open-drain or open-collector
output devices connected in a wired OR configuration.
3. SCL (Serial Clock Input) Pin
The SCL pin is used for serial clock input. It is capable of processing signals at the rising and falling edges
of the SCL clock input signal. Make sure the rising time and falling time conform to the specifications.
4. WP Pin
In the S-24C08A and the S-24C16A, this pin is used for write protection. When there is no need for write
protection, connect the pin to the GND; when there is a need for write protection, connect the pin to the
Vcc.

Operation
1. Start Condition
When the SCL line is "H," the SDA line changes from "H" to "L." This allows the device to go to the start
condition.
All operations begin from the start condition.
2. Stop Condition
When the SCL line is "H," the SDA line changes from "L" to "H." This allows the device to go to the stop
condition.
When the device receives the stop condition signal during a read sequence, the read operation is
interrupted, and the device goes to standby mode.
When the device receives the stop condition signal during write sequence, the retrieval of write data is
halted, and the EEPROM initiates rewrite
.
3. Data Transmission
Changing the SDA line while the SCL line is "L" allows the data to be transmitted. A start or stop condition
is recognized when the SDA line changes while the SCL line is "H."

4. Acknowledgment
The unit of data transmission is 8 bits. By turning the SDA line "L," the slave device mounted on the
system bus which receives the data during the 9th clock cycle outputs the acknowledgment signal
verifying the data reception.
When the EEPROM is rewriting, the device does not output the acknowledgment signal.
5. Device Addressing
To perform data communications, the master device mounted on the system outputs the start condition
signal to the slave device.
Next, the master device outputs 7-bit length device address and a 1-bit length
read/write instruction code onto the SDA bus.
Upper 4 bits of the device address are called the "Device Code," and set to "1010." Successive 3 bits (P2, P1, P0)
are called the "Page Address." (In the S-24C08A, P2 is Slave Address A2.) Any of memory blocks (the S-24C08A
has four 256-byte memory blocks and the S-24C16A has eight 256-byte memory blocks) can be selected at P2, P1,
and P0.

6. Write
6.1 Byte Write
When the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code
"0," following the start condition signal, it outputs the acknowledgment signal. Next, when the
EEPROM receives an 8-bit length word address, it outputs the acknowledgment signal.
After the EEPROM receives 8-bit write data and outputs the acknowledgment signal, it receives the
stop condition signal. Next, the EEPROM at the specified memory address starts to rewrite.
When the EEPROM is rewriting, all operations are prohibited and the acknowledgment signal is not
output.
6.2 Page Write
Up to 16 bytes per page can be written in the S-24C08A and S-24C16A.
Basic data transmission procedures are the same as those in the "Byte Write." However, when the
EEPROM receives 8-bit write data which corresponds to the page size, the page can be written.
When the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code
"0," following the start condition signal, it outputs the acknowledgment signal. When the EEPROM
receives an 8-bit length word address, it outputs the acknowledgment signal.
After the EEPROM receives 8-bit write data and outputs the acknowledgment signal, it receives 8-
bit write data corresponding to the next word address, and outputs the acknowledgment signal. The
EEPROM repeats reception of 8-bit write data and output of the acknowledgment signal in
succession. It is capable of receiving write data corresponding to the maximum page size.
When the EEPROM receives the stop condition signal, it starts to rewrite, corresponding to the size
of the page, on which write data, starting from the specified memory address, is received.

Page Write
In the S-24C08A or S-24C16A, the lower 4 bits at the word address are automatically incremented
each when the EEPROM receives 8 bit write data.
Even when the write data exceeds 16 bytes, the upper 4 bits of the word address and page address
(P2, P1, P0) remain unchanged, and the lower 4 bits are rolled over and overwritten.
6.3 Acknowledgment Polling
Acknowledgment polling is used to know when the rewriting of the EEPROM is finished.
After the EEPROM receives the stop condition signal and once it starts to rewrite, all operations are
prohibited. Also, the EEPROM cannot respond to the signal transmitted by the master device.
Accordingly, the master device transmits the start condition signal and the device address read/write
instruction code to the EEPROM (namely, the slave device) to detect the response of the slave
device. This allows users to know when the rewriting of the EEPROM is finished.
That is, if the slave device does not output the acknowledgment signal, it means that the EEPROM is
rewriting; when the slave device outputs the acknowledgment signal, you can know that rewriting
has been completed. It is recommended to use read instruction "1" for the read/write instruction
code transmitted by the master device.
6.4 Write Protection
The S-24C08A and the S-24C16A are capable of protecting the memory. When the WP pin is
connected to V
CC
, writing to all memory area is prohibited.
When the WP pin is connected to GND, the write protection becomes invalid, and writing in all
memory area becomes available. However, when there is no need for using write protection, always
connect the WP pin to GND.

Read
7.1 Current Address Read
The EEPROM is capable of storing the last accessed memory address during both writing and
reading. The memory address is stored as long as the power voltage is more than the retention
voltage V
AH
.
Accordingly, when the master device recognizes the position of the address pointer inside the
EEPROM, data can be read from the memory address of the current address pointer without
assigning a word address. This is called"Current Address Read"
"Current Address Rea" is explained for when the address counter inside the EEPROM is an "n"
address.
When the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code
"1," following the start condition signal, it outputs the acknowledgment signal. However, in the S-
24C08A/16A, page address (P1, P0)/(P2, P1, P0) becomes invalid, and the memory address of the
current address pointer becomes valid.
Next, 8-bit length data at an "n" address is output from the EEPROM, in synchronization with the
SCL clock.
The address counter is incremented at the falling edge of the SCL clock by which the 8th bit of data
is output, and the address counter goes to address n+1.
The master device does not output the acknowledgment signal and transmits the stop condition
signal to finish reading
.
For recognition of the address pointer inside the EEPROM, take into consideration the following:
The memory address counter inside the EEPROM is automatically incremented for every falling edge of the SCL
clock by which the 8th bit of data is output during the time of reading. During the time of writing, upper bits
of the memory address (upper 4 bits of the word address and page address) are left unchanged and are
not incremented.

7.2 Random Read
Random read is a mode used when the data is read from arbitrary memory addresses.
To load a memory address into the address counter inside the EEPROM, first perform a dummy write according to
the following procedures:
When the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code
"0," following the start condition signal, it outputs the acknowledgment signal.
Next, the EEPROM receives an 8-bit length word address and outputs the acknowledgment signal.
Last, the memory address is loaded into the address counter of the EEPROM.
the EEPROM receives the write data during byte or page writing. However, data reception is not performed during
dummy write.
The memory address is loaded into the memory address counter inside the EEPROM during dummy
write. After that, the master device can read the data starting from the arbitrary memory address by
transmitting a new start condition signal and performing the same operation as that in the "Current
Read."
That is, when the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction
code "1," following the start condition signal, it outputs the acknowledgment signal.
Next, 8-bit length data is output from the EEPROM, in synchronization with the SCL clock. The
master device does not output an acknowledgment signal and transmits the stop condition signal to
finish reading.

7.3 Sequential Read
When the EEPROM receives a 7-bit length device address and a 1-bit read/write instruction code "1" in
both current and random read operations, following the start condition signal, it outputs the
acknowledgment signal
When 8-bit length data is output from the EEPROM, in synchronization with the SCL clock, the memory address
counter inside the EEPROM is automatically incremented at the falling edge of the SCL clock, by which
the 8th data is output.
When the master device transmits the acknowledgment signal, the next memory address data is output.
When the master device transmits the acknowledgment signal, the memory address counter inside the
EEPROM is incremented and read data in succession. This is called "Sequential Read."
When the master device does not output an acknowledgement signal and transmits the stop condition
signal, the read operation is finished.
Data can be read in the "Sequential Read" mode in succession. When the memory address counter
reaches the last word address, it rolls over to the first memory address.

8. Address Increment Timing
The address increment timing is as follows. See Figures 15 and 16. During reading operation, the memory
address counter is automatically incremented at the falling edge of the SCL clock (the 8th read data is
output).
During writing operation, the memory address counter is also automatically incremented at the
falling edge of the SCL clock when the 8th bit write data is fetched.
