描述 Description

The CXA2503AR is an IC designed exclusively to drive color LCD panels LCX005BK/BKB and LCX009AK/AKB.

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.
