描述 Description

The CXA3503R 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 a 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.
