2. LCD drivers
LH5073A
and
LH5074F
LCD drivers LH5073A and
LH5074F,
as display common drivers,
respectively include 32 drive circuits. The display duty is
1132.
As
display segment drivers, they include 98 drive circuits and store 8bit
parallel display data sent from a microcomputer into their internal
display RAM to generate liquid crystal drive signal. One bit data of the
disply RAM corresponds to one dot ON/OFF of the liquid crystal
panel.

Difference between LH5073A and LH5074F
LH5073 is equipped with an internal oscillation circuit and aninter-
nal
booster circuit.
LH5074 has no internal oscillation circuit (Synchronization signal
is inputted from
LH5073A),
and no booster circuit (Voltageis
sup-
plid
from
LH5073A).
* The control signal array of LH5073A is contrary to that of
LH5074F.
