SSD1854

This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal precautions to be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation it is recommended that V_in and V_out be constrained to range V_SS < or = (V_in or V_out) < or = V_DD. Reliability of operation is enhanced if unused inputs are connected to an appropriate logic voltage level (e.g. either V_SS or V_DD). Unused outputs must be open. This device may be light sensitive. Caution should be taken to avoid exposure of this device any light source during normal operation. This device is not radiation protected.

SSD1854 is a single-chip CMOS 4 gray scale LCD driver with controller for liquid crystal dot-matrix graphic display system. It consists of 288 high voltage driving output pins for driving maximum 128 Segments and 160 Commons, customized for 2-sides COF modules.

SSD1854 displays data directly from its internal 128x176x2 bits Graphic Display Data RAM (GDDRAM). Data/Commands are sent from general MCU through a hardware selectable 6800-/8080- series compatible Parallel Interface or 3/4 wires Serial Peripheral Interface.

SSD1854 designed with multi-line-addressing (MLA) scheme to improve the display quality and reduce the system power consumption.

SSD1854 embeds a DC-DC Converter, a LCD Voltage Regulator, an On-Chip Bias Divider and an On-Chip oscillator, which reduce the number of external components. With the special design on minimizing power consumption and die/package layout, SSD1854 is suitable for any portable batterydriven applications requiring a long operation period and a compact size.
