64CH COMMON DRIVER FOR DOT MATRIX LCD
FUNCTIONAL DESCRIPTION
RC Oscillator
The RC Oscillator generates CL2, M, FRM of the S6B0107, and CLK1 and CLK2 of the S6B0108 by the oscillation
resister R and capacitor C.
When selecting the master/slave mode, the oscillation circuit is as following:
Master Mode: In the master mode, use these terminals as shown below.
Slave Mode: In the slave mode, stop the oscillator as shown below.
Timing Generation Circuit
It generates CL2, M, FRM, CLK1 and CLK2 by the frequency from the oscillation circuit.
Selection of Master/Slave (M/S) Mode
– When M/S is "H", it generates CL2, M, FRM, CLK1 and CLK2 internally.
– When M/S is "L", it operates by receiving M and CL2 from the mater device
Frequency Selection (FS)
To adjust FRM frequency by 70Hz, the oscillation frequency should be as follows:
In the slave mode, it is connected to V
