GRAPHICS S1D13781 S1D13781 WQVGA Graphics Controller 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 S1D13781s 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. Its 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. n FEATURES 384KByte Embedded Memory General Purpose IO Pins Direct and Indirect CPU Interfaces LUT 256wordx24bitx3pcs for both Main and PIP 8/16-bit data bus width layer SPI CPU interface Alpha Blending, Transparency, Flashing Support for single panel implementation: 2D BitBLT - RGB Interface TFT panel Software initiated Power Save Mode - Color and Monochrome STN H/PIOVDD: 3.3 or 1.8V, CORE/PLLVDD: 1.5V Programmable resolutions (up to 800x480 8bpp) Clocks can be selected from embedded PLL or and color depth (up to 24 bpp) digital clock inputs Multiple Window (Layer) support for Main and PIP Temperature Range: -40 ~ 85 Rotation (Swivel View) 90/180/270 Package: QFP100-pin, 0.5mm pin pitch n SYSTEM BLOCK DIAGRAM TFT, CSTN Control Signals Host S1D13781 CPU S1D13781 Features Embedded display buffer 2 layer support Alpha Blending and Transparency PIP layer Flashing Programmable PLL X94A-C-001-01 1 Revision 1.1GRAPHICS S1D13781 n DESCRIPTION CPU Interface 384KByte Embedded Memory Support for most popular CPU interfaces Maximum Resolution for WQVGA: Direct/Indirect Addressing 1 layer: 480x272 at 24bpp or 8/16-bit interface support 800x480 at 8bpp SPI 2 layer: Main 480x272 at 16bpp and PIP 480x272 at 8bpp Display Support Miscellaneous Single panel implementation can be: RGB Interface TFT panel 2D BitBLT Color and Monochrome STN Internal System Speed: TBD Programmable resolutions up to 800x480 8bpp Software initiated power save mode Programmable color depths up to 24 bpp Multiple General Purpose IO pins Flexible clock structure: Display Features Embedded PLL Multiple Window (Layer) support for Main and PIP Digital clock inputs Alpha Blending and Transparency Operating Temperature Range: -40 ~ 85 PIP Flashing Low Operating Voltage: LUT 256wordx24bitx3pcs for both Main and PIP PLL/CORE 1.5 volts and VDD layer PIO/HIO 3.3 or 1.8 volts VDD Rotation (Swivel View) 90/180/270 Package: QFP 100-pin, 0.5mm pin pitch CONTACT YOUR SALES REPRESENTATIVE FOR THESE COMPREHENSIVE DESIGN TOOLS S1D13781 Technical CPU Independent S1D13781 Evaluation Royalty Free source level Documentation Software Utilities Boards driver code Japan North America Taiwan China Seiko Epson Corporation Epson Electronics America, Inc.
