Description

The CXA2543R is an IC designed exclusively to drive the color LCD panel DCX501BK and LCX018AK.

This IC greatly reduces the number of circuits and parts required to drive LCD panels by incorporating RGB decoder functions for video signals, driver functions, and a timing generator for driving panels onto a single chip.

This chip has a built-in serial interface circuit and electronic attenuators which allow various mode settings and adjustments to be performed through direct control from an external microcomputer, etc.
