TW8816 TECHWELL Controller

TW8816 Overview

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.
