SSD1905 Datasheet | Solomon Systech

DESCRIPTION The SSD1905 is a graphics controller with built-in 80Kbyte SRAM display buffer, supporting color and mono LCD. The SSD1905 can support a wide range of active and passive panels, and interface with various CPUs. The advanced design, together with integration of memory and timing circuits make a low cost, low power, single chip solution to meet the handheld devices or appliances market needs, such as Pocket/Palm-size PCs and mobile munication devices. The SSD1905 supports most of the resolutions monly used in portable applications, and is featured with hardware display rotation, covering different form factor needs. The controller also features Virtual Display, Floating Window (variable size Overlay Window) and two Cursors to reduce the software manipulation. The 32bit internal data path provides high bandwidth display memory for fast screen updates. The SSD1905 also provides the advantage of a single power supply. The SSD1905 features low-latency CPU access, which supports microprocessors without READY/WAIT# handshaking signals. This controller impartiality to CPU type or operating system makes it an ideal display solution for a wide variety of applications. The SSD1905 is available in a 100 pin TQFP package.
