描述 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.
