Overview

Description

Support is limited to customers who have already adopted these products.

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.
