August 2007
The S1D13742 is a color LCD graphics controller with an embedded 768K byte display buffer. The S1D13742
supports a 8/16-bit Intel 80 CPU architecture while providing high performance bandwidth into display memory
allowing for fast screen updates.
Products requiring a rotated display image can take advantage of the SwivelView™ feature which provides
hardware rotation of the display memory transparent to the software application. Resolutions supported include
800x480 single buffered and 352x416 double buffered.
The S1D13742 uses a double-buffer architecture to prevent any visual tearing during streaming video screen
updates.
■ FEATURES
