SSD1805 Datasheet | Solomon Systech

Description SSD1805 is a single-chip CMOS LCD driver with controller for dot-matrix graphic liquid crystal display system. SSD1805 consists of 200 high-voltage driving output pins for driving maximum 132 Segments, 68 mons / 132 Segments, 64 mons and 1 icon-driving mon / 132 Segments, 54 mons and 1 icon-driving mon / 132 Segments, 32 mons and 1 icon-driving mon. SSD1805 can also be switched among 32, 54, 64 or 68 display multiplex ratios by hardware pin selection. SSD1805 consists of 132 x 68 bits Graphic Display Data RAM (GDDRAM). Data/mands are sent from mon MCU through 8-bit 6800-series / 8080-series patible Parallel Interface or 4-wires Serial Peripheral Interface by software program selections. SSD1805 embeds DC-DC Converter, On-Chip Oscillator and Bias Divider to reduce the number of external ponents. With the advance design, low power consumption, stable LCD operating voltage and flexible die package layout, SSD1805 is suitable for any portable battery-driven applications requiring long operation period with pact size. 2 FEATURES - Power Supply: VDD = 1.8V - 3.6V VDDIO = 1.2V - VDD VCI = VDD - 3.6V - LCD Driving Output Voltage: VLCD = +12.5V - Low Current Sleep Mode - Pin selectable 68/64/54/32 multiplex ratio configuration.
