... The SDA line is usually pulled up to the V devices. 3. SCL (Serial Clock Input) Pin The SCL pin is used for serial clock input. Since signals are processed at the rising or falling edge of the SCL clock input signal, attention should be paid to the rising time and falling time to conform to the specifications. ...

Page 10

... Every operation begins from a start condition. 2. Stop Condition Stop is identified by a low to high transition of the SDA line while the SCL line is stable at high. When a device receives a stop condition during a read sequence, the read operation is interrupted, and the device enters standby mode. ...

Page 11

... SDA 4. Acknowledge The unit of data transmission is 8 bits. During the 9th clock cycle period the receiver on the bus pulls down the SDA line to acknowledge the receipt of the 8-bit data. When an internal write cycle is in progress, the device does not generate an acknowledge. ...

Page 12

... The successive 1 bit (P0) is used to define a page address and choose the two 256-byte memory blocks (Address 000h to 0FFh and 100h to 1FFh). In S-24CS08A, successive 1 bit is called the “Slave Addrdess”. This 1 bit is used to identify a device on the system bus and is compared with the predetermined value which is defined by the address input pin (A2). ...

... Write 6. 1 Byte Write When the master sends a 7-bit device address and a 1-bit read / write instruction code set to "0", following a start condition, the E address and responds with an acknowledge. After the E with an acknowledge, it receives a stop condition and that initiates the write cycle at the addressed memory ...

Page 14

... In S-24CS04A, the lower 4 bits of the word address are automatically incremented every time when the 2 E PROM receives 8-bit write data. If the size of 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 previously received data will be overwritten. ...

Page 15

... When the WP pin is connected to the GND, the write protection is invalid, and write operation in all memory area is available. Fix the level of the WP pin from the rising edge of SCL for loading the last write data (D0) until the end of the write time (10 ms max.). If the WP pin changes during this time, the address data being written at this time is not guaranteed ...

... In the read operation the memory address counter in the E falling edge of the SCL clock for the 8th bit of the output data. In the write operation, on the other hand, the upper bits of the memory address (the upper bits of the word address and page address) unchanged and are not incremented at the falling edge of the SCL clock for the 8th bit of the received data ...

The E address and responds with an acknowledge. The memory address is loaded to the address counter in the 2 E PROM by these operations. Reception of write data does not follow in a dummy write whereas reception of write data follows in a byte write and in a page write ...

... PROM incremented and makes it possible to read data in succession. This is called "Sequential Read". The master device outputs stop condition not an acknowledge , the reading of E Data can be read in succession in the sequential read mode. When the memory address counter reaches the last word address, it rolls over to the first memory address. ...

Page 19

... For example, even if a reset signal is input to the microprocessor, the internal circuit of the E reset as long as the stop condition is not input to the E same status and cannot shift to the next operation. This symptom applies to the case when only the microprocessor is reset when the power supply voltage drops. With this status, if the power supply voltage ...

... SDA pin and SCL pin noise suppression time The S-24CS01A/02A/04A/08A includes a built-in low-pass filter to suppress noise at the SDA and SCL pins. This means that if the power supply voltage is 5.0 V, noise with a pulse width of 160 ns or less can be suppressed. The guaranteed for details, refer to noise suppression time (t ...

Page 27

... When write data is input more than defined page size at page write operation, for example, S-24CS04A (which can be executed 16-byte page write) is received data more than 17 byte, 8-bit data of the 17th byte is over written to the first byte in the same page. Data over the capacity of page address cannot be written. 10.
