11 / 11 page LC717A00AR No.A2048-11/11 ●nCS Interface selection / Chip-select-inverting input (SPI) Selection of I2C compatible bus mode or SPI mode is through this terminal. After initialization, the LSI is automatically in I2C compatible bus mode. To continually use I2C compatible bus mode, fix nCS pin to “High”. To switch to SPI mode after LSI initialization, change the nCS input “High” → “Low”. The nCS pin is used as the chip- select-inverting input pin of SPI, and SPI mode is kept until LSI is again initialized. If interface is not to be used, fix the pin to “High”. ●nRST It is the external-reset-signal-inverting-input pin. When nRST pin is “Low”, LSI is in the reset state. Each pin (Cin0 to 7, Cref, Pout,0 to 7, ERROR) is “Hi-Z” during reset state. ●SDA/SI Data input and output (I2C) / Data input (SPI) It is the data input and output pin of the I2C compatible bus or the data input pin of the SPI depending on the mode of operation. If interface is not to be used, fix the pin to “High”. However, even if interface is not to be used, providing a communication terminal on board is still recommended. ●SA/SO Slave address selection (I2C) / Data output (SPI) It is the slave address selection pin of the I2C compatible bus or the data output pin of the SPI depending on the mode of operation. If interface is not to be used, fix the pin to “High”. However, even if interface is not to be used, providing a communication terminal on board is still recommended. PS SANYO Semiconductor Co.,Ltd. assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor Co.,Ltd. products described or contained herein. Regarding monolithic semiconductors, if you should intend to use this IC continuously under high temperature, high current, high voltage, or drastic temperature change, even if it is used within the range of absolute maximum ratings or operating conditions, there is a possibility of decrease reliability. Please contact us for a confirmation. SANYO Semiconductor Co.,Ltd. strives to supply high-quality high-reliability products, however, any and all semiconductor products fail or malfunction with some probability. It is possible that these probabilistic failures or malfunction could give rise to accidents or events that could endanger human lives, trouble that could give rise to smoke or fire, or accidents that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.
