DESCRIPTION
The STV9420/21is an ONSCREEN DISPLAY for
monitor. It is built as a slave peripheralconnected
to a host MCU via a serial I
2
C bus. It includes a
display memory, controls all the display attributes
and generatespixels from the data read in its on
chip memory. The line PLL and a special slice
interpolator allow to have a display aspect which
doesnotdependonthelineandframefrequencies.
I
2
C interface allows MCU to make transparent in-
ternal accessto preparethe next pagesduringthe
display of the current page. Toggle from onepage
to anotherby programmingonly one register.
4 x 8 bits PWM DAC are available (STV9421) to
provide DC voltage control to other peripherals.
The STV9420/21providesthe user an easy to use
and costeffectivesolution to displayalphanumeric
or graphicinformation on monitorscreen.
