SSD1906 Datasheet | Solomon Systech

DESCRIPTION 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 munication devices. The SSD1906 supports most of the mon resolutions for portable appliances and features hardware display rotation, covering various form factor requirements. 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.
