CHARACTER BY CHARACTER COLOR SELECTION (UP TO 8 DIFFERENT COLORS) PROGRAMMABLE BACKGROUND (COLOR, TRANSPARENT OR WITH SHADOWING) CHARACTER BLINKING 2-WIRES ASYNCHRONOUS SERIAL MCU INTERFACE (I2C PROTOCOL) 8 x 8 BITS PWM DAC OUTPUTS SINGLE POSITIVE 5V SUPPLY SHRINK 24 (Plastic Package) ORDER CODE : STV9422 DESCRIPTION The STV9422/24 is an ON SCREEN DISPLAY .

Features

MCU via a serial I2C 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. I2C interface allows MCU to make transparent internal access to prepare the next pages during the display of the current page. Toggle from one page to another by programming only one register. 8 x 8 bits PWM DAC are available to provide DC voltage control to other peripherals. The STV9422/24 provides the user.
