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
