Easy 32-Segment Driver circuit

This device is easy way for control 32-Segment display
by three control lines

AY0438 32-Segment CMOS LCD Driver
The AY0438 is a CMOS integrated device that drives a liquid crystal
display, usually under microprocessor control. The part acts as a
smart peripheral that drives up to 32 LCD segments. It needs only
three control lines due to its serial input construction. It latches the
data to be displayed and relieves the microcontroller from the task of

generating the required waveforms.
