S1D13781 Graphics Controller

S1D13781 BoosterPack LCDC development package from Epson

Image of EPSON's S1D13781 Graphics ControllerEpson's S1D13781 is a simple, multi-purpose Graphics LCD Controller with 384 KByte embedded SRAM display buffer, supporting 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 480 x 272 at 24 bpp or 800 x 480 at 8 bpp for single layer displays, or 480 x 272 at 16 bpp (main layer) and 480 x 272 at 8 bpp (PIP layer) for two-layer displays.

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. 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.
