Basic Rules x This IC, I2C-bus, is designed to correspond to the Standard-mode (100 kbps) and Fast-mode(400 kbps) devices in the version 2.1 of Philips Co.'s specification. However, it does not correspond to the HS-mode (to 3.4 Mbps). x This IC will be operated as a slave device in the I2C-bus system. x The program operation check of this IC has not been conducted on the multi-master bus system and the mix-speed bus system, yet. The connected confirmation of this IC to the CBUS receiver also has not been checked. Please confirm our company if it will be used in these mode systems. x Purchase of Panasonic I2C Components conveys a license under the Philips I2C patent right to use these components in an I2C systems, provided that the system conforms to the I2C standard specifications as defined by Philips. 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 a START condition. A Low to High transition on the SDA line while SCL is High defines a STOP condition. START and STOP conditions are always generated by the master. After START condition occur, the bus will be busy. The bus is considered to be free again a certain time after the STOP condition. STOP condition START condition SDA SCL 3. Transferring Data 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.

Precaution in setup of I2C-bus data 1) Power on a) All data must be set on IC when the power supply is tuned on. (SUB ADD : 00H to 07H) b) IF limit amplifier must be ON at the time of the initial data transfer of I2C. (SUB ADD : 04H, D7 = "1") c) The power supply transition time (VCC1, 2 = 0 → 9 V) must be more than 10 ms. d) Electric current flows in the power supply off condition when a power supply is connected to the TUNED terminal (Pin 21). Therefore, be careful in the case of the backup mode such as a microcomputer. 2) Pin 16 Don't use Pin 16 (ZAP). It must be open. 3) Monitor function a) Pin 21 of this IC has a function to monitor internal circuit terminals of this IC. The monitor point of analog signal or digital signal is set by SUBADD : 04H, D0 to D3. The choice of monitor point of logic signal is SUBADD : 0AH .It is chosen by D0 to D2 of 0AH. b) Don't choose more than one monitor point (analog, logic) at the same time. c) It is prohibited choosing the monitor point when IF limit amplifier is compulsory off (SUBADD : 04H, D7 = "0"). Be sure to turn on IF limit amplifier when you use monitor function. d) Monitor function is a function for the test purpose only in our company, and its function is not guaranteed. When it is needed to send data, all data must be "0". Don't use it with the actual tuner set. 4) Charge pump test function a) SUBADD : 04H D4 to D5 are the bits for the function check of charge pump. For a normal use, they must be set to "0". 5) Handling unused bits a) All unused bits must be set to "0". When it is necessary to input Subaddress data, all unused bits must be set to "0". 6) Set number of N divider Don't establish N value about settlement of N divider in 271 or less. 7) The timing of IF counter IF counter starts to count when it detects Stop condition of write mode at SDS mode (SUB ADD : 01H, D1 = "1"). The result of the IF count can get it when it begins to read it after the progress about more than 70 ms and it is made the mode and begins to read it. To prevent IF counter’s abnormal function, so that stop condition may not come between about 70 ms of the following. (see the figure below.) Even if this timing isn't kept, IC doesn't become uncontrollable. But the following condition are occurred by the transmitting data. a) When there are data which turn off SDS : Counter stops, and it is reset. The judgment result of IF counter isn't right. Ignore data and erase it. b) In the case of the dummy data: Stop condition is ignored, and IF counter works as it is. (It isn't reset.) If an original access prohibition time passes, the proper result of IF counter is obtained. Wait time Gate time reset Start (stop condition) Access prohibition time : More than 70 ms.

This IC is intended to be used for general electronic equipment [Home audio tuner]. Consult our sales staff in advance for information on the following applications: x 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. x 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 2. Pay attention to the direction of LSI. When mounting it in the wrong direction onto the PCB (printed-circuit-board), it might smoke or ignite. 3. 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. 4. Perform a visual inspection on the PCB before applying power, otherwise damage might happen due to problems such as a solderbridge 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. 5. Take notice in the use of this product that it might break or occasionally smoke when an abnormal state occurs such as output pinVCC short (Power supply fault), output pin-GND short (Ground fault), or output-to-output-pin short (load short) . And, 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. 6. When designing your equipment, comply with the range of absolute maximum rating and the guaranteed operating conditions (operating power supply voltage and operating environment etc.). Especially, please be careful not to exceed the range of absolute maximum rating on the transient state, such as power-on, power-off and mode-switching. Otherwise, we will not be liable for any defect which may arise later in your equipment. Even when the products are used within the guaranteed values, take into the consideration of incidence of break down and failure mode, possible to occur to semiconductor products. Measures on the systems such as redundant design, arresting the spread of fire or preventing glitch are recommended in order to prevent physical injury, fire, social damages, for example, by using the products. 7. When using the LSI for new models, verify the safety including the long-term reliability for each product. 8. When the application system is designed by using this LSI, be sure to confirm notes in this book. Be sure to read the notes to descriptions and the usage notes in the book.
