LC75813T Datasheet | SANYO

Overview The LC75813E and LC75813T are 1/3 duty and 1/4 duty general-purpose LCD drivers that can be used for frequency display in electronic tuners under the control of a microcontroller. The LC75813E and LC75813T can drive an LCD with up to 344 segments directly. The LC75813E and LC75813T can also control up to 8 general-purpose output ports. Since the LC75813E and LC75813T use separate power supply systems for the LCD drive block and the logic block, the LCD driver block power-supply voltage can be set to any voltage in the range 2.7 to 6.0 volts, regardless of the logic block power-supply voltage. Features - Switching between 1/3 duty and 1/4 duty drive techniques under serial data control. - Switching between 1/2 bias and 1/3 bias drive techniques under serial data control. - Up to 261 segments for 1/3 duty drive and 344 segments for 1/4 duty drive can be displayed. - Serial data input supports CCB format munication with the system controller. - Serial data control of the power-saving mode based backup function and all the segments forced off function. - Serial data control of switching between the segment output port and the general-purpose output port functions.
