DESCRIPTION

The STV9422/24 is an ON SCREEN DISPLAY for

monitor. It is built as a slave peripheral connected

to a host 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 in-

ternal 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 an easy to use

and cost effective solution to display alphanumeric

or graphic information on monitor screen.
