S5D2501F Datasheet | Samsung Semiconductor

JAN. 2000 DATA SHEET OSD PROCESSOR FOR MONITORS OVERVIEW The S5D2501F is used to display some characters or symbols on a screen of monitor. Basically, the operation is to control the internal memory on chip and generate the R,G,B signals for some characters or symbols. The R,G,B signals are synchronized with the horizontal sync. Then the R,G,B signals are mixed with the main video signal in the Video Amp IC. The font data for characters or symbols are stored in the internal ROM. This stored data are accessed and controlled by the control data from a micro controller. The control data are transmitted through the I2C bus. All timing control signals including the system clock are synchronized with the horizontal sync. Therefore there is a PLL circuitry on chip. 24-DIP-300 Features ORDERING INFORMATION - - Build in 1K-byte SRAM 464 ROM fonts (448 standard fonts + 16 Multi-color fonts) - - - - - - - - - - - - - - - - - - - Full Screen Memory Architecture Wide range PLL available (15 k Hz - 120 k Hz) Programmable vertical height of character Programmable vertical and horizontal positioning Character color selection up to 16 different colors Programmable background color (Up to 16 colors) Character blinking, bordering and shadowing Color blinking Character scrolling Fade-in and fade-out Row to row spacing control Window outline and shadowing Box drawing Character sizing up to four times 8 PWM DAC channels with 8-bit resolution 96 MHz pixel frequency from on-chip PLL I2C Protocol Data Transmission (Slave Address : BAH) OSD Vertical Bouncing Auto Detect / Correction Back Raster Blanking (Row Control) Device Package Operating Temperature 0°C - 70°C S5D2501F 24-DIP-300 OSD PROCESSOR FOR MONITORS BLOCK DIAGRAM SDA 7 SCL 8 Data Receiver PWM 16 Data RAM Data 16 RAM (480 x 16) ROM Addr 9 Control 16 Data Font...
