August 2009
The S1D13781 is a simple, multi-purpose Graphics LCD Controller with 384KByte embedded SRAM display
buffer which supports both RGB interface TFT and CSTN panels. The S1D13781 supports most popular CPU
interfaces in both 8/16-bit and Direct/Indirect variations. The embedded display buffer allows WQVGA up to
480x272 at 24bpp or 800x480 8bpp for single layer display, or 480x272 at 16bpp (Main Layer) and 480x272 at
8bpp (PIP Layer) for two layer display.
The S1D13781’s combination of multiple CPU interfaces and display interface types offers a versatile, yet easy to
develop display system. Additionally, it offers Multiple Window support, Transparency and Alpha Blending
functions, as well as 2D BitBLT functions. It is a flexible, low cost, low power, single chip solution designed to meet
the demands of embedded markets such as low end IP phone devices where total system cost and battery life
are major concerns. It’s impartiality to CPU type or operating system also makes it an ideal display solution for a
wide variety of other applications such as Office Automation and Factory Automation applications.
