Reset active (/RES pin = “L”)
VDD – VSS power OFF
Set the time (tL) from reset
active to turning off the VDD -
VSS power (VDD - VSS = 1.8V)
longer than the time (tH) when
the potential of V5 ~ V1
becomes below the threshold
voltage (approximately 1V) of
the LCD panel. For tH, refer to
the <Reference Data> of this
event. When tH is too long,
insert a resistor between V5
and VDD to reduce it.
Notes: Reference items
*14: The logic circuit of this IC’s power supply VDD - VSS controls the driver of the LCD power supply VDD - V5. So, if the
power supply VDD - VSS is cut off when the LCD power supply VDD - V5 has still any residual voltage, the driver
(COM. SEG) may output any uncontrolled voltage. When turning off the power, observe the following basic
procedures:
• After turning off the internal power supply, make sure that the potential V5 ~ V1 has become below the threshold
voltage of the LCD panel, and then turn off this IC’s power supply (VDD - VSS). 6. Description of Function, 6.7 Power

*15: After inputting the power save command, be sure to reset the function using the /RES terminal until the power
supply VDD - VSS is turned off. 7. Command Description (20) Power Save
*16: After inputting the power save command, do not reset the function using the /RES terminal until the power supply
VDD - VSS is turned off. 7. Command Description (20) Power Save
