S1D13517 External SDRAM LCD Controller
S1D13517
March 2009
The S1D13517 is a color LCD graphics controller which uses an external SDRAM display buffer. The S1D13517
supports an 8/16-bit indirect host interface while providing high performance bandwidth to external SDRAM,
allowing for fast screen updates.
The S1D13517 supports displays up to 960x540 (QHD) @ 24 bpp or 800x600 (SVGA)@ 24bpp, controlling a main
the window and up to two Picture-in-Picture windows. Additionally, the S1D13517 is designed with a 2D Graphics
Engine with Alpha Blending. The S1D13517 uses a double-buffer architecture to prevent any visual tearing during
streaming video screen updates.
