Solomon Systech (Distribution: Gleichmann Electronics) has introduced the SSD1961 graphic controller for mobile applications including smartphones and portable media players (PMPs), but also for energy sensitive applications such as room temperature controllers or controls for window blinds. The SSD1961 supports resolutions of up to 640 x 480 pixels (VGA) at up to 18-bit color depth. Furthermore, key product features of the device include 675 Kbytes of embedded display SRAM, which serves as frame buffer between the host processor and the LCD display.
The on-chip integrated LCD and MCU interfaces reduce the wiring effort to a minimum. The SSD1961 supports different types of monochrome, color, active and passive LCD displays including 4/8-bit monochrome/color STNs, 12/18-bit active matrix TFTs and 16-bit HR TFTs with 160 x 160 pixels and 320 x 240 pixels. The universal built parallel 8/16-bit controller interface enables the connection of CPUs from different manufacturers.
The SSD1961 contains an integrated graphic engine, which allows display rotation of 90°, 180° and 270°. The hardware implemented display rotation is significantly more efficient than the usual software solutions, where the content of the display buffer must be entirely rewritten every time. The graphic engine also supports “Virtual Display” mode. This allows viewing of portions from a larger image by means of panning and scrolling of the display. Furthermore, the implemented “Floating Window” mode enables the overlaying of various size windows on the main window. For improved image quality, brightness, contrast and color saturation can each be separately set and programmed.
To extend the battery life in mobile applications, the SSD1961 uses an innovative dynamic backlight control technology. The sophisticated algorithm of this technology helps to reduce backlight power consumption by up to 50%.
The four general-purpose inputs/outputs (GPIOs) require a supply voltage of between 1.8 V and 3.3 V and the controller core itself 1.2 V. The SSD1961, with dimensions of only 5 mm x 5 mm, is available in a 64-pin TFBGA (Thin Fine-pitch Ball Grid Array) package.
Solomon Systech has announced that in the fourth quarter of 2008 it will introduce a further graphic controller, which will support the new WVGA (Wide VGA) with 800 x 480 pixels resolution and 24-bit color depth.
About Gleichmann & Co. Electronics GmbH
Since its foundation in 1979, Gleichmann & Co. Electronics GmbH, in the same company group with MSC Vertriebs GmbH, has established itself as one of the leading pan European distributors of electronic components. One of the reasons for the high acceptance by customers and suppliers is the company’s early focus on comparatively few, highly sophisticated products such as microcontrollers, programmable logic devices, graphic displays and customized battery solutions. The deep technical know-how of our sales engineers and field applications engineers enable us to implement complete new designs right up to the manufactured product to satisfy customers’ requests. Owning two ASIC design centers, a research laboratory and one of Europe’s largest, state-of-the-art programming facilities, Gleichmann & Co Electronics GmbH leads the way in custom design services.
