CXA2503AR
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
electronic attenuators which allow various mode
settings and adjustments to be performed through
direct control from an external microcomputer, etc.
