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.
