TW8827中文资料用于模拟 LCD 面板的低成本、高度集成的 LCD 控制器数据手册Renesas规格书

描述 Description

The TW8827 is an ultra low cost, highly integrated LCD TFT flat panel controller supporting analog panels. To reduce BOM cost, TW8827 integrates a NTSC/PAL/SECAM video decoder supporting CBVS & S-Video inputs, an 8-bit MCU, a CCFL controller and a LED controller. The TW8827 integrates a high quality NTSC/PAL/SECAM 2D video decoder and a 2D De-interlacer/Scaler. In addition, 16-bit digital RGB/YCbCr inputs are supported through built-in digital interface.
