CXA3272R
Driver/Timing Generator for Color LCD Panels
Description
The CXA3272R is an IC designed to drive the color
LCD panels LCX032 and LCX033.
This IC greatly reduces the number of peripheral
circuits and parts by incorporating an RGB driver
and timing generator for video signals onto a single
chip. This chip has a built-in serial interface circuit
and electronic attenuators which allow various
settings to be performed by microcomputer control,
etc.
