PCA85132
LCD driver for low multiplex rates
Internal clock — To enable the internal oscillator, pin OSC has to be connected to V SS .
Pin CLK then becomes an output. For further information on the internal clock, see
Section 7.1.6.2 .
External clock — To enable the use of an external clock, pin OSC has to be connected to
V DD . Pin CLK then becomes an input for the external clock frequency f clk(ext) . For further
information on the external clock, see Section 7.1.6.3 .
Figure 3 illustrates the frequency generation of the PCA85132.

Remark: A clock signal must always be supplied to the device. Removing the clock may
freeze the LCD in a DC state, which is not suitable for the liquid crystal.

Internal clock
If the internal oscillator is used, the timing of the PCA85132 is derived from the built-in
oscillator by a pre-scaler which can be configured with the frequency-ctrl command (see
Table 12 ).
The internal oscillator is calibrated within an accuracy of ±3.9 % (at V DD = 5.0 V;
T amb = 30 °C).
The frequency-ctrl command determines the division factor between the oscillator
frequency f osc and the internal clock frequency f clk(int) . If the internal oscillator is used, the
frame frequency is derived from the internal clock frequency f clk(int) by the fixed division
shown in Equation 1 on page 10 .
If the display is enabled (see bit E in Table 6 ), f clk(int) on pin CLK provides the clock signal
for cascaded LCD drivers in the system. For further information about cascading, see
Section 14.4 on page 44 . The value range of f osc is specified in Table 22 on page 38 .
External clock
If the external clock source is selected, the timing frequency of the PCA85132 is the
external clock frequency. In this case, the frequency-ctrl command has no influence on
the clock frequency nor the frame frequency. The frame frequency is derived from the
external clock frequency f clk(ext) by the fixed division as shown in Equation 1 .
