4K Color STN Driver & Controller IC AR3301
GENERAL DESCRIPTION
Ar3301 is a single chip driver and controller device for dot matrix LCD (liquid
crystal display) display systems. This chip can be directly connected to a
microprocessor, accepts serial or 8/16bit parallel display data from the
microprocessor, stores the display data in a built-in display RAM and
generates LCD driving signals.
AR3301 has 128 X RGB segment outputs and 162 common outputs, so
that it can drive 128X162 dots 256/4096-color STN LCD panel.
AR3301 is best suited to drive LCD systems for batteryoperated, handheld
information equipment by ensuring low power consumption and a wide range
of operating voltages.
