• 4/8-bit monochrome STN interface.
• 4/8-bit color STN interface.
• 9/12/18-bit Active Matrix TFT interface.
• Direct support for 18-bit Sharp HR-TFT interface (160x160, 320x240).
• 1/2/4/8/16 bit-per-pixel (bpp) color depths.
• Up to 64 gray shades using Frame Rate Control (FRC) and dithering on monochrome passive LCD panels.
• Up to 256k colors on passive STN panels.
• Up to 256k colors on active matrix LCD panels.
• Resolution examples :
   320x320 at a color depth of 16 bpp
   160x160 at a color depth of 16 bpp
   160x240 at a color depth of 16 bpp
• Display Rotation Mode: 90°, 180°, 270° counter-clockwise hardware rotation of display image.
• Virtual Display Support: displays image larger than the panel size using panning and scrolling.
• Floating Window Mode: displays a variable size window overlaid on the background image.
• 2 Hardware Cursors (for 4/8/16 bpp): simultaneously displays two cursors overlaid on the background image.
• Double Buffering/Multi-pages: provides smooth animation and instantaneous screen updates

Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the limits in the Electrical Characteristics tables or Pin Description section.

The SSD1906 is a graphics controller with built-in 256Kbyte SRAM display buffer, supporting color and mono LCD. The SSD1906 can support a wide range of active and passive panels and interface with various CPUs. The advanced design, together with integrated memory and timing circuits produces a low cost, low power, single chip solution for handheld devices or appliances, including Pocket/Palm-size PCs and mobile communication devices.

The SSD1906 supports most of the common resolutions for portable appliances and features hardware display rotation, covering various form factor equirements. The controller also features Virtual Display, Floating Window (variable size Overlay Window) and two Cursors to reduce software manipulation. The 32-bit internal data path provides high bandwidth display memory for fast screen updates and the SSD1906 also provides the advantage of a single power supply.

The SSD1906 features low-latency CPU access, supporting microprocessors without RDY#/WAIT# handshaking signals. This impartiality to CPU type or operating system makes the controller an ideal display solution for a wide variety of applications. The SSD1906 is available in a 100 pin TQFP & TFBGA package.
