!"Description:
ST7065C is a segment/common driver for dot
matrix type LCD display. It features 40 channels
with 20 X 2 bits bi-directional shift registers, data
latches, LCD drivers and logic control circuits. It
is fabricated by high voltage CMOS process with
low current consumption.
The ST7065C can convert serial data received
from a LCD controller, such as ST7066U, into
parallel data and send out LCD driving
waveforms to the LCD panel. The ST7065C is
designed for general-purpose LCD drivers. It can
drive both static and dynamic drive LCD. The LSI
can be used as segment/common driver.
The ST7065C has pin function compatibility with
the KS0065B that allows the user easily to
replace it with a ST7065C.

ST7065C
Both Channels 1 and 2 used as common drivers (FCS=0)
When both channels 1 and 2 of the ST7065C are used as common drivers, the FCS is
set low and the signals (CL1, CL2, M) from the controller are connected as shown in
the following figure.
