1 / 20 page  STV9427 STV9428-STV9429 HIGH SPEED MULTISYNCH ON-SCREEN DISPLAY FOR MONITOR June 1998 . CMOS SINGLE CHIP OSD FOR MONITOR . BUILT IN 1 KBYTE RAM HOLDING : - CHARACTER CODES - USER DEFINABLE CHARACTERS . 207 ALPHANUMERIC CHARACTERS OR GRAPHIC SYMBOLS IN INTERNAL ROM . 12 x 18 CHARACTER DOT MATRIX . PROGRAMMABLE ACCENTUATED CHARAC- TER SET . CHARACTER BLINKING . RAM DEFINABLE COLOR LOOK UP TABLE . UP TO 16 USER DEFINABLE CHARACTERS . UP TO 80MHz PIXEL CLOCK . INTERNAL HORIZONTAL PLL (15 TO 120kHz) . PROGRAMMABLE VERTICAL HEIGHT OF CHARACTER WITH A SLICE INTERPOLATOR TO MEET MULTI-SYNCH REQUIREMENTS . PROGRAMMABLE VERTICAL AND HORI- ZONTAL POSITIONING . FLEXIBLE SCREEN DESCRIPTION . 22 CONTROL CODES FOR POWERFULL SERIAL ATTRIBUTES . 2-WIRES ASYNCHRONOUS SERIAL MCU INTERFACE (I 2C PROTOCOL) . 8 x 8 BITS PWM DAC OUTPUTS . SINGLE POSITIVE 5V SUPPLY DIP16 (Plastic Package) ORDER CODE : STV9427 DESCRIPTION The STV9427/28/29 is an ON SCREEN DISPLAY for monitor. It is built as a slave peripheral con- nected to a host MCU via a serial I 2C bus. It includes a display memory, controls all the display attributes and generates pixels from the data read in its on chip memory. The line PLL and a special slice interpolator allow to have a display aspect which does not depend on the line and frame frequencies. I 2C interface allows MCU to make transparent internal access to prepare the next pages during the display of the current page. Tog- gle from one page to another by programming only one register. DIP24 (Plastic Package) ORDER CODE : STV9429 8 x 8 bits PWM DAC are available to provide DC voltage control to other peripherals. The STV9427/28/29 provides the user an easy to use and cost effective solution to display alphanu- meric or graphic information on monitor screen. DIP20 (Plastic Package) ORDER CODE : STV9428 1/20 |
