The SAA6712E is a graphics engine, which converts
digital RGB data into video signals suitable for TFT
displays. It supports SXGA input resolution as well as true
colour. Independent horizontal and vertical up and
downscaling can display the input data arbitrarily on the
connected TFT display. Auto-scan capability allows the
applied graphics mode to be detected.
Overlay signals can be generated either by an internal
OSD generator or supplied via the overlay port from an
external OSD controller.

The SAA6712E must be embedded into a system
containing a microcontroller with an I
interface. For auto-scan capabilities a frame buffer built
from SGRAM or SDRAM is needed. The size of this frame
buffer depends on the maximum resolution and bandwidth
needed for the application. For converting the analog RGB
stream into a digital data stream one or two ADCs with
3 channels each for R, G and B are needed.
