Chapter 15 Power Supply Circuit (POWER)
15 – 4
OPTION B (D): 1.5 V (3.0 V), With regulator
circuit for LCD bias
OPTION A (C): 1.5 V (3.0 V), Without regulator
circuit for LCD bias
15.3.2 Operation of the OPTION A Power Supply Circuit
The battery voltage (V
DD
) is supplied to the different voltage regulator circuits (V/R1 and V/R2) of the OPTION A.
The output voltages of the voltage regulator circuits are used as the internal logic power supply (V
CH
) and the
power supply voltage (V
XT
) for the low-speed clock generator circuit. Further, the battery voltage is connected
directly to the power supply of the high-speed clock generator circuit.
The output voltage of the voltage regulator V/R1 is supplied as the power supply (V
CH
) for the internal logic
circuits during low-speed clock operation.
The output voltage of the voltage regulator circuits V/R2 and V/R3 are always supplied respectively as the power
supply voltage (V
XT
) for the low-speed clock generator circuit and the reference voltage (V
DD1
) for the LCD bias
generator circuit.
