Decoder/Driver/Timing Generator for Color LCD Panels

For the availability of this product, please contact the sales office.

Description

The CXA2503AR is an IC designed exclusively to

64 pin LQFP (Plastic)

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
