Note1. Power-down / Reset
- When it is not used, set this pin to low. (e.g., pull-down to GND by a resistor (10kohm) ) .
- RST-pin is not made pull-up or pull-down inside of device.
Note2. Device address setting
Pull-down VSOUT/A0-pin to GND by a resistor (10kohm) : Device address will be 1001100.
Pull-up VSOUT/A0-pin to VDD by a resistor (10kohm) : Device address will be 1001101.
- In case of pull-up, connect a resistor to VDD.
- Don’t connect VSOUT/A0-pin to the input pin with bus hold circuit of the subsequent device (Device address can’t be
acquired properly).
- VSOUT-pin is not made pull-up or pull-down inside the device, so please be sure to connect the resistor to this pin.
Note3. SYNC Signal Input
- The outside circuit should be designed not to apply higher voltage above absolute maximum rating (PVD+3.6v) to the
digital input pins when power is not supplied,
- Fix the input level when there is no sync signal on the sync input pins (e.g., pull-down to GND by resistor (10kohm) ) .
