Oscillator
The HD66410 incorporates an R-C oscillator with low power-dissipation, in which the oscillation
frequency can be adjusted by appropriate selection of oscillator resistor R
f
and capacitor C
f
. The adjusted
clock signal is used for system internal circuits; thus, if this oscillator is not used, an appropriate clock
signal must be externally input through the CR pin. In this case, the C and R pins must be left unconnected.
Figure 22 shows oscillator connections.
Clock and Frame Frequency
The HD66410 generates the frame frequency (LCD drive frequency) by dividing the input clock frequency
by 132. The division ratio is the same for all LCD duty cycles.
The frame frequency is usually 70 to 90 Hz; when the frame frequency is 80 Hz, for example, the input
clock frequency must be 10.56 kHz.

Clock
The oscillation frequency can be
adjusted by varying the oscillator
resistor (R
) and capacitor (C
).
If the R
or C
value is increased,
or power supply voltage is decreased,
the oscillationfrequency decreases.
For the relationship between the R
f
value, C
f
value, and oscillationfre
quency, see the Electrical
Characteristics section.
