This LSI, I2C-bus, is designed to correspond to the Standard-mode (100 kbps) and Fast-mode(400 kbps) devices in the version 2.1 of NXP's specification. However, it does not correspond to the HS-mode (to 3.4 Mbps). This LSI will be operated as a slave device in the I2C-bus system. This IC will not operate as a master device. The program operation check of this LSI has not been conducted on the multi-master bus system and the mix-speed bus system, yet. The connected confirmation of this LSI to the CBUS receiver also has not been checked. Please confirm with our company if it will be used in these mode systems. The I2C is the brand of NXP. 2) START and STOP conditions A High to Low transition on the SDA line while SCL is High is one such unique case. This situation indicates START condition. A Low to High transition on the SDA line while SCL is High defines STOP condition. START and STOP conditions are always generated by the master. After START condition occurs, the bus will be busy. The bus is considered to be free again a certain time after the STOP condition. Every byte put on the SDA line must be 8-bits long. The number of bytes that can be transmitted per transfer is unrestricted. Each byte has to be followed by an acknowledge bit. Data is transferred with the most significant bit (MSB) first.

- When using the LSI for new models, verify the safety including the long-term reliability for each product. 2. When the application system is designed by using this LSI, please confirm the notes in this book. Please read the notes to descriptions and the usage notes in the book. 3. Please use this product in compliance with all applicable laws and regulations that regulate the inclusion or use of control led substances, including without limitation, the EU RoHS Directive. Our company shall not be held responsible for any damage incurred as a result of our IC being used by our customers, not complying with the applicable laws and regulations. 4. Pay attention to the direction of LSI. When mounting it in the wrong direction onto the PCB (printed-circuit-board), it migh t emit smoke or ignite. 5. Pay attention in the PCB (printed-circuit-board) pattern layout in order to prevent damage due to short circuit between pins . In addition, refer to the Pin Description for the pin configuration. 6. Perform a visual inspection on the PCB before applying power, otherwise damage might happen due to problems such as a solder-bridge between the pins of the semiconductor device. Also, perform a full technical verification on the assembly quality , because the same damage possibly can happen due to conductive substances, such as solder ball, that adhere to the LSI during transportation. 7. Take notice in the use of this product that it might be damaged or occasionally emit smoke when an abnormal state occurs such as output pin-VCC short (Power supply fault), output pin-GND short (Ground fault), or output-to-output-pin short (load short). Safety measures such as an installation of fuses are recommended because the extent of the above-mentioned damage and smoke emission will depend on the current capability of the power supply.. 8. This IC is intended to be used for general electronic equipment. Consult our sales staff in advance for information on the following applications: Special applications in which exceptional quality and reliability are required, or if the failure or malfunction of this IC may directly jeopardize life or harm the human body. Any applications other than the standard applications intended. (1) Space appliance (such as artificial satellite, and rocket) (2) Traffic control equipment (such as for automobile, airplane, train, and ship) (3) Medical equipment for life support (4) Submarine transponder (5) Control equipment for power plant (6) Disaster prevention and security device (7) Weapon (8) Others : Applications of which reliability equivalent to (1) to (7) is required Our company shall not be held responsible for any damage incurred as a result of or in connection with the IC being used for any special application, unless our company agrees to the use of such special application. 9. This IC is neither designed nor intended for use in automotive applications or environments unless the specific product is designated by our company as compliant with the ISO/TS 16949 requirements. Our company shall not be held responsible for any damage incurred by customers or any third party as a result of or in connection with the IC being used in automotive application, unless our company agrees to such application in this book. 10. Due to the unshielded structure of this LSI, functions and characteristics of the product cannot be guaranteed under the exposure of light. During normal operation or even under testing condition, please ensure that the LSI is not exposed to light . 11. Please ensure that your design does not have metal shield parts touching the chip surface as the surface potential is GND voltage. 12. Pay attention to the breakdown voltage of this LSI when using.
