DATA SHORT FN8593 TW8823C Rev. 2.00 August 16, 2019 TFT Flat Panel Controller with Built-In 3D Video Decoder, Triple ADCs, Dual PIP, and 16-Bit OSD Support Digital horizontal PLL and advanced synchronization The TW8823C incorporates many of the features processing for VCR playback and weak signal required to create a multi-purpose in-car LCD display performance. system into a single package. It integrates a high-quality Programmable hue, brightness, saturation, contrast, 3D comb NTSC/PAL/SECAM video decoder, triple high sharpness speed RGB ADCs, high-quality scaler, bit-mapped OSD, triple DACs and image enhancement functions that High quality horizontal and vertical filtered down include features such as Black and White Stretch and scaling with arbitrary scale down ratio favorite color enhancement. It also supports panoramic scaling for conversion to wide screen display format. On ANALOG RGB INPUTS the input side, it supports a rich combination of CVBS, Triple high-speed 10-bit ADCs with clamping and S-video, analog RGB, and digital YCbCr/RGB. On the programmable gain amplifier output side, it supports both digital and analog panel types with its built-in timing controller and analog RGB SOG and H/V sync support for YPbPr or RGB input output. In addition, the TW8823C supports LVDS type Built-in line locked PLL with sync separator panels. Supports analog input resolution up to 1080i or WXGA The TW8823C also has two PIP (Picture-in-Picture) DUAL DIGITAL INPUTS SUPPORT engines that can display three display sources simultaneously in a single window. It also has a built-in Dual channel digital inputs support with following bit-mapped OSD with 16-bit color depth and an combination: acceleration function. It can also accept 18-bit external 1-channel 18/16-bit inputs and 1-channel 8-bit OSD inputs. In addition, TW8823C has a built-in inputs high-performance microcontroller with cache. Its SPI interface supports various serial flash types. 1-channel 24-bit digital RGB/YCbCr inputs Supports both 656 and 601 video formats Features Allows connection to external HDMI receiver ANALOG VIDEO DECODER BUILT-IN MICROCONTROLLER NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N Built-in 8052 MCU up to 72MHz clock combination), PAL (60), SECAM with automatic format Built-in code cache memory to enhance CPU detection performance Two 10-bit ADCs and analog clamping circuit Supports Single/Dual/Quad IO SPI Flash with 24-bit/32-bit addressing Fully programmable static gain or automatic gain control for the Y or CVBS channel System programming through UART Programmable white peak control for the Y or CVBS Supports SPI DMA Read/Write to OSD memory channel 2 Supports I C Master interface with GPIO Software selectable analog inputs allows either Supports two UART interface up to 115200bps and composite or S-video input 8 bytes RX FIFO High quality motion adaptive 3D comb filter for both Supports IR receiver and interrupt output NTSC and PAL with concurrent 3D noise reduction Supports 24-bit contiguous addressing mode PAL delay line for color phase error correction Image enhancement with 2D dynamic peaking and CTI Digital sub-carrier PLL for accurate color decoding FN8593 Rev. 2.00 Page 1 of 2 August 16, 2019 TFT PANEL SUPPORT DDR-SDRAM Supports 16 bits 155MHz DDR-SDRAM up to 256Mb Built-in both analog and digital timing controller with programmability HOST INTERFACE Supports optional single channel LVDS panel with resolution up to WXGA, 80MHz Supports 2-wire serial bus interface Supports 3, 4, 6, or 8 bits per pixel up to 16.8 million Supports 8-bits Parallel Host Interface colors with built-in dithering engine CLOCK GENERATION Supports analog panel with resolution up to WQVGA 20MHz Frequency synthesizer with spread spectrum generate DDR memory and display clocks ON SCREEN DISPLAY Spread spectrum profile based on triangular Supports three window bitmapped OSD, one 16 bits modulation with center spread and two 8 bits bitmap OSD Modulation frequency and spread width can be selectable Built-in OSD controller with Bit-Blit Engine Supports a variety of functions including blinking, POWER MANAGEMENT transparency, and blending Supports Panel power sequencing Supports External OSD with external alpha blending Supports DPMS for monitor power management Supports OSD compression 1.8/2.5V/3.3 V operation Supports window width up to 1366 MISCELLANEOUS IMAGE PROCESSING Built-in single CCFL backlight controller High quality scaler with both up/down and nonlinear Built-in single LED backlight controller scaling support Built-in touch screen controller with 12-bit ADC Built-in 2D de-interlacing function Power-down mode Programmable hue, brightness, saturation, contrast Single 27MHz crystal Sharpness control with vertical peaking up to +12db 216 Ld LQFP package Programmable color transient improvement control TW8823AT-LC2-GE is AEC-Q100 qualified Programmable cropping of input video and graphics Independent RGB gain and offset controls Applications Panorama/water-glass scaling In-car display controller DTV hue adjustment Portable DVD and DVRs players Programmable 10-bit Gamma correction for each Portable media player color Operated in Frame Sync mode only Black/white stretch Programmable favorite color enhancement PIP FUNCTION Two independent PIPs Variable sub-window size POP with alpha blending Supports both 16-bit YPbPr and RGB data format High quality up and down scaling engine for PIP FN8593 Rev. 2.00 Page 2 of 2 August 16, 2019
