Doubler
Doubles the voltage through oscillating frequency of the CR Oscillating Circuit. The voltage is boosted from the VSS level and
output to VOUT. Capacitors between C1+ and C1- as well as between VSS and VOUT are connected.
Use the doubler in the
range of VDD
≤3.6 V.

LCD Voltage Adjustment Circuit
LCD drive voltage V can be adjusted by the following two voltage controllers:
R Voltage Regulator
Adjusts voltage regulator output VLCD by externally- divided resistors Ra and Rb.
VLCD can be calculated as the division ratio of the internal reference voltage VREF. VREF has temperature
characteristics of approx. 0.01%/ C and -0.13%/ C and the LCD temperature gradient can be compensated. VREF
differs depending upon the temperature characteristics of the reference voltage to select a command.
VLCD can be used as a “variable” by using the volume resistor as the divided resistor. Feedback voltage noises
occurring at VCNT pin directly affect VLCD. Take appropriate measures against noises.
