INTRODUCTION The S6B0718 is a driver & controller LSI for graphic dot-matrix liquid crystal display systems. It contains 81 common and 104 segment driver circuits. This chip is connected directly to a microprocessor, accepts serial or 8-bit parallel display data and stores in an on-chip display data RAM of 89 x 104 bits. It provides a highly flexible display section due to 1-to-1 correspondence between on-chip display data RAM bits and LCD panel pixels. And it performs display data RAM read/write operation with no externally operating clock to minimize power consumption. In addition, because it contains power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components. FEATURES Driver Output Circuits - 81 common outputs / 104 segment outputs Applicable Duty Ratios - Various partial display - Partial window moving & data scrolling On-chip Display Data RAM - Capacity: 89 x 104 = 9,256 bits - Bit data "1": a dot of display is illuminated. - Bit data "0": a dot of display is not illuminated. Microprocessor Interface - 8-bit parallel bi-directional interface with 6800-series or 8080-series - Serial interface (only write operation) available On-chip Low Power Analog Circuit - On-chip oscillator circuit - Voltage converter (x3, x4, x5 or x6) - Voltage regulator (temperature coefficient: -0.05%/°C or external input) - On-chip electronic contrast control function (64 steps) - Voltage follower (LCD bias: 1/4 to 1/11) Operating Voltage Range - Supply voltage (VDD): 2.4 to 3.6 V - LCD driving voltage (VLCD = V0 - VSS): 4.0 to 15.0 V Low power Consumption - 150 μA Max. (VDD = 3V, x5 boosting, V0 = 12V, internal power supply on and display OFF) - 15 μA Max. (during power save [standby] mode) Package Type - Gold bumped chip or TCP
