TW8823C中文资料TFT Flat Panel Controller with Built-in 3D Video Decoder, Triple ADCs, Dual PIP and 16-bit OSD Support数据手册Renesas规格书

描述 Description

The TW8823C incorporates many of the features required to create a multi-purpose in-car LCD display system into a single package. It integrates a high-quality 3D comb NTSC/PAL/SECAM video decoder, triple High-Speed RGB ADCs, high-quality scaler, bit-mapped OSD, triple DACs and image enhancement functions that include features such as Black and White Stretch and favorite color enhancement. It also supports panoramic scaling for conversion to wide screen display format. On the input side, it supports a rich combination of CVBS, S‑video, analog RGB, and digital YCbCr/RGB. On the output side, it supports both digital and analog panel types with its built-in timing controller and analog RGB output.

In addition, the TW8823C supports LVDS type panels. The TW8823C also has two PIP (Picture-in-Picture) engines that can display three display sources simultaneously in a single window. It also has a built-in bit-mapped OSD with 16-bit color depth and an acceleration function. It can also accept 18-bit external OSD inputs. In addition, TW8823C has a built-in high‑performance microcontroller with cache. Its SPI interface supports various serial flash types.
