STV3550
LCD and Matrix Display Integrated Up-convertor with 32-bit CPU
DATA BRIEF

FEATURES Fully-programmable digital video output stage for direct rgb interface to flat display panel with 4- to 10-bit color resolution and pixel resolution from VGA to WXGA including HDTV2.

Progressive display mode (60 Hz, 50 Hz) for full-screen graphic planes Mosaic mode with up to 16 pictures displayed Picture compositor to provide transparency mode between video and graphic planes Gamma correction

Versatile integrated up-converter 50/60-Hz progressive output with lineinterpolation: (A + A*), field-merging (A + B) or with motion-adaptive de-interlacing based on median f(A, B) Advanced still picture modes: AA*AA* and ABAB interlaced or AAAA non-interlaced Automatic movie mode detection and scanning

High-performance 8-bit bitmap OSD generator Pixel-based resolution with 10-bit RGB outputs Programmable resolution up to WXGA, all standard displays are supported: teletext 1.5 (480x520) and 2.5 (672x520), double-page teletext (960x520) with picture-and-text, teleWeb (640x480) 4 graphic planes with full alpha-blending capabilities: 24-bit background plane, 10-bit RGB video plane, bitmap OSD plane with color map, up to 128 x 128 pixel cursor plane 2D graphics accelerator

Standard definition input ITU-R BT.656/601 video input Separate H/V inputs synchronous with input clock 3D temporal noise reduction with cometeffect correction Movie mode detection with motion phase recovery Scene-change detector for contrast enhancer and up-conversion control Letterbox format detection and auto-format correction

Embedded 32-bit ST20 CPU core Peripherals and I/Os for TV chassis control: 30 fully-programmable I/Os (5V tolerant) 4 external interrupts, 8-bit programmable PWM with 4 inputs/ outputs Infrared digital preprocessor Real time clock and watchdog timer Four 16-bit standard timers 10-bit ADC with 6 inputs and wake-up capability 2 Master/slave I C bus interfaces UART and support for IrDA interfaces

High-quality video display Picture structure improvement including: color transition improvement, Luma peaking/ coring and Luma contrast enhancer H/V format conversion with zoom in/out (4x to 1/8x) with H/V decimation Letterbox and 4:3 to 16:9 format conversion with programmable 5-segment panoramic mode Very flexible Sync generator for master and slave modes by Vsync and Hsync signals generation
