MC141803 is a CMOS LCD Driver which consists of 4 annunciator outputs and 153 high voltage LCD driving signals (33 commons and 120 segments). MC141803 is split common output design. It has parallel interface capability for operating with general MCU. Besides the general LCD driver features, it has an on chip LCD bias Voltage Generator circuit such that fewer external components are required during application. Single Supply Operation, 2.4 V - 3.5 V Operating Temperature Range : -30 to 85°C Low Current Stand-by Mode (<500nA) On Chip Bias Voltage Generator 8 Bit Parallel Interface Graphic Mode Operation On Chip 120 x 33 Graphic Display Data RAM 120 Segment Drivers, 33 Common Drivers Selectable 1/16, 1/32, 1/33 Multiplex Ratio Selectable on Chip Voltage Doubler and Tripler Selectable 1:5 or 1:7 Bias Ratio Re-mapping of Row and Column Drivers Four Stand Alone Annunciator (Static Icon) Driver Circuits Low Power Icon Mode Driven by Com32 in Special Driving Scheme Selectable LCD Driving Voltage Temperature Coefficients 16 Level Internal Contrast Control External Contrast Control Provided Master Clear RAM Standard TAB Package
