1. Summary
The LH1562F4 is a 240 output
segment/common
driver
LSI suitable
for driving
large scale dot matrix
LC panels using as personal
computers/work
stations.
Through the use of SST (Super Slim TCP) technology,
it is ideal
for
substantially
decreasing
the size of the frame section
of the LC module.
The LH1562F4 is good both segment driver
and common driver,
and a low power
high-precision
LC panel display
can be assembled.

In case of segment mode, the data input
is selected
4bit parallel
input
mode
and 8bit parallel
input mode by a mode(MD) pin.
In case of common mode, data input/output
pins are bidirectional,
four data
shift
directions
are pin-selectable.
