FN7762
Rev.1.00
September 26, 2013
LCD Flat Panel Processor with built-in MCU, NTSC/PAL/SECAM Decoder, T-CON
and Analog RGB Support
The TW8816 is a highly integrated multi-purpose LCD display
solution for both analog and digital panels. To reduce BOM
cost, TW8816 integrates an 8-bit MCU and a CCFL controller.
Through multiple input ports, TW8816 can directly display
video and graphic content from a variety of devices including
TV Tuners, DVD players, back-up cameras, DTV/DMB receivers
and navigation/GPS receivers.
