DESCRIPTION

The STV9420/21is 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 notdependon theline andframefrequencies.

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.

(Plastic Package)

ORDER CODE : STV9421

4 x 8 bits PWM DAC are available (STV9421) to

provide DC voltage control to other peripherals.

The STV9420/21provides the user an easy to use

and cost effective solution to display alphanumeric

or graphicinformation on monitor screen.
