KS0107B 64CH COMMON DRIVER FOR DOT MATRIX LCD
FUNCTIONAL DESCRIPTION
1. RC Oscillator
The RC Oscillator generates CL2, M, FRM of the KS0107B, and CLK1 and CLK2 of the KS0108B by the oscillation resister
R and capacitor C.
When selecting the master/slave mode, the oscillation circuit is as following:
1) Master Mode : in the master mode, use these terminals as shown below.
Internal Oscillation External Clock
2) Slave Mode : in the slave mode, stop the oscillator as shown below.
2. Timing Generation Circuit
It generates CL2, M, FRM, CLK1 and CLK2 by the frequency from the oscillation circuit.
1) Selection of Master/Slave (M/S) Mode
When M/S is ° H± it generat es CL2 M FRM CLK and CLK2inter na l
When M/S is °L± it operat es beceiving M and CL2 from the master device.
2) Frequency Selection (FS)
To adjust FRM frequency by 70 Hz, the oscillation frequency should be as follows:
