Address Input Pins (A0, A1, and A2) Connect pins A0, A1, and A2 to the GND or the VCC, respectively, to assign slave addresses. There are 8 different ways to assign slave addresses in the S-24C01A and S-24C02A through a combination of pins A0, A1, and A2, and 4 ways to assign them in the S-24C04A through a combination of pins A1 and A2. 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 VCC 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 VCC, 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. TEST/WP Pin The S-24C01A does not have a write protection (WP) function. The pin serves as a TEST pin and shoud always be connect to the GND. In the S-24C02A and S-24C04A, 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. 6 Seiko Instruments Inc. Rev. 2.2_30 Operation 1. Start Condition CMOS 2-WIRE SERIAL EEPROM S-24C01A/02A/04A 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. tSU.STA tHD.STA tSU.STO SCL SDA Start Condition Stop Condition Figure 6 Start/Stop Conditions 3. Data Transmission Changing the SDA line while the SCL line is "L" allows the data to be transmitted.

Acknowledgment Rev. 2.2_30 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.

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 are called the "Slave Address." It is used to select a device on the system bus, and compared to the predetermined address value at the address input pin (A2, A1, or A0). When the comparison results match, the slave device outputs the acknowledgment signal during the 9th clock cycle.

So, "A0" becomes "P0." "P0" is a page address bit and is equivalent to an additional uppermost bit of the word address. Accordingly, when P0="0," the former half area corresponding to 2 kbits (addresses from 000h to 0FFh) in the entire memory are selected; when P0="1," the latter half area corresponding to 2 kbits (addresses from 100h to 1FFh) in all areas of the memory are selected. 8 Seiko Instruments Inc. Rev. 2.2_30 6. Write 6.1 Byte Write CMOS 2-WIRE SERIAL EEPROM S-24C01A/02A/04A 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.

Up to 16 bytes per page can be written in the S-24C04A. 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 8bit 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.

Even if the write data exceeds 8 bytes, the upper 5 bits at the word address remain unchanged, the lower 3 bits are rolled over and overwritten. In the S-24C04A, 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 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-24C02A and the S-24C04A are capable of protecting the memory. When the WP pin is connected to VCC, writing to 50% of the latter half of all memory area (080h to 0FFh in the S-24C02A; 100h to 1FFh in the S-24C04A) is prohibited. Even when writing is prohibited, since the controller inside the IC is operating, the response to the signal transmitted by the master device is not available during the time of writing (tWR). 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. 10 Seiko Instruments Inc. Rev. 2.2_30 7. Read 7.1 Current Address Read CMOS 2-WIRE SERIAL EEPROM S-24C01A/02A/04A 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 VAH. 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 Read" 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 S24C04A, page address 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.

During the time of writing, upper bits of the memory address (upper 5 bits of the word address in the S-24C01A and S-24C02A; upper 4 bits of the word address and page address P0 in the S-24C04A) are left unchanged and are not incremented. Seiko Instruments Inc. 11 CMOS 2-WIRED SERIAL EEPROM S-24C01A/02A/04A 7.2 Random Read Rev. 2.2_30 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.

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.
