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.

(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.
